How to Create Fancy Text with Unicode

Unicode's Mathematical Alphanumeric Symbols block and other areas contain bold, italic, script, Fraktur, monospace, and double-struck variants of Latin letters that can transform ordinary text into stylized versions without any formatting. This guide explains how Unicode fancy text works, which character ranges produce which styles, and the accessibility trade-offs of using them.

·

If you have ever seen text like 𝕳𝖊𝖑𝖑𝖔 or 𝓗𝓮𝓵𝓵𝓸 or ⓗⓔⓛⓛⓞ or HELLO on social media and assumed it was a special font, here is the surprising truth: those are ordinary Unicode characters, not any kind of formatting or font change. They appear in search results, bios, and notifications exactly as typed because they are just characters — the same as any letter or emoji. This guide explains how Unicode fancy text works, which character ranges create which styles, and the practical and accessibility considerations you should keep in mind.

What Makes This Possible: Mathematical Alphanumeric Symbols

Unicode was designed to encode every character needed for mathematics and science, and mathematicians use letters in many typographic variants: bold, italic, bold-italic, script (calligraphy), Fraktur (blackletter), double-struck (blackboard bold), and monospace. Unicode 3.1 added an entire block called Mathematical Alphanumeric Symbols (U+1D400–U+1D7FF) containing these variants.

The block contains complete alphabet sets in:

Style Example A–Z Unicode Range
Mathematical Bold 𝐀–𝐙 𝐚–𝐳 U+1D400–U+1D433
Mathematical Italic 𝐴–𝑍 𝑎–𝑧 U+1D434–U+1D467
Mathematical Bold Italic 𝑨–𝒁 𝒂–𝒛 U+1D468–U+1D49B
Mathematical Script 𝒜–𝒵 𝒶–𝓏 U+1D49C–U+1D4CF
Mathematical Bold Script 𝓐–𝓩 𝓪–𝔃 U+1D4D0–U+1D503
Mathematical Fraktur 𝔄–𝔜 𝔞–𝔷 U+1D504–U+1D537
Mathematical Double-Struck 𝔸–𝕐 𝕒–𝕫 U+1D538–U+1D56B
Mathematical Bold Fraktur 𝕬–𝖅 𝖆–𝖟 U+1D56C–U+1D59F
Mathematical Sans-Serif 𝖠–𝖹 𝖺–𝗓 U+1D5A0–U+1D5D3
Mathematical Sans-Serif Bold 𝗔–𝗭 𝗮–𝘇 U+1D5D4–U+1D607
Mathematical Sans-Serif Italic 𝘈–𝘡 𝘢–𝘻 U+1D608–U+1D63B
Mathematical Monospace 𝙰–𝚉 𝚊–𝚣 U+1D670–U+1D6A3

There are also numeric variants in many of these styles. This means you can write an entire paragraph in "bold script" or "Fraktur" and it will display that way everywhere — including in plain-text environments like Twitter bios, Instagram captions, and Discord chat where rich formatting is impossible.


Here is the phrase "Hello World" rendered in each major Unicode fancy text style:

Beyond Mathematical Symbols: Other "Fancy" Unicode Ranges

Circled Letters and Numbers

The Enclosed Alphanumerics block (U+2460–U+24FF) contains circled variants:

  • Uppercase: Ⓐ Ⓑ Ⓒ … Ⓩ (U+24B6–U+24CF)
  • Lowercase: ⓐ ⓑ ⓒ … ⓩ (U+24D0–U+24E9)
  • Numbers: ① ② ③ … ⑳ (U+2460–U+2473), ㉑–㊿ for 21–50

The Enclosed Alphanumeric Supplement block (U+1F100–U+1F1FF) adds more variants including negative (filled) circles: 🅐 🅑 🅒 … 🅩 (U+1F150–U+1F169).

Fullwidth Latin Letters

Fullwidth characters are double-width variants of ASCII characters used in East Asian typography:

  • A–Z: A B C … Z (U+FF21–U+FF3A)
  • a–z: a b c … z (U+FF41–U+FF5A)
  • 0–9: 0 1 2 … 9 (U+FF10–U+FF19)

These characters are used to make Latin text fit into fixed-width CJK grids. In creative text, they give a distinctive "aesthetic" or "vaporwave" look.

Small Capitals

Small capital letters are scattered across the Latin Extended and Phonetic Extensions blocks, as they are used in the International Phonetic Alphabet (IPA) and linguistic notation.

Common small caps:

Normal Small Cap Code Point
A U+1D00
B ʙ U+0299
E U+1D07
G ɢ U+0262
H ʜ U+029C
I ɪ U+026A
K U+1D0B
L ʟ U+029F
M U+1D0D
N ɴ U+0274
O U+1D0F
P U+1D18
R ʀ U+0280
T U+1D1B
U U+1D1C
W U+1C9D or U+0057 variant
Y ʏ U+028F
Z U+1D22

Not all letters have a dedicated small capital form — coverage is incomplete, which can make fully small-caps text look inconsistent.

Superscript and Subscript

Unicode includes superscript and subscript digits and some letters:

Superscripts: - Digits: ⁰ ¹ ² ³ ⁴ ⁵ ⁶ ⁷ ⁸ ⁹ - Letters: ⁱ ⁿ ᵃ ᵇ ᶜ ᵈ ᵉ ᶠ ᵍ ʰ ʲ ᵏ ˡ ᵐ ᵒ ᵖ ʳ ˢ ᵗ ᵘ ᵛ ʷ ˣ ʸ ᶻ

Subscripts: - Digits: ₀ ₁ ₂ ₃ ₄ ₅ ₆ ₇ ₈ ₉ - Letters: ₐ ₑ ₒ ₓ ₔ ᵢ ᵣ ᵤ ᵥ

Coverage for superscript and subscript letters is partial — this is by design, as Unicode only added letters that appear in established scientific and linguistic notation.


Combining Characters and Diacritics for "Glitch" Text

Unicode combining characters are diacritics and marks that attach to the preceding base character. Stacking many of these creates the "zalgo" or "glitch" text effect seen in internet culture.

Combining diacritics occupy the Combining Diacritical Marks block (U+0300–U+036F):

Character Effect Code Point
̀ Grave above U+0300
́ Acute above U+0301
̂ Circumflex above U+0302
̃ Tilde above U+0303
̈ Diaeresis above U+0308
̷ Short solidus overlay U+0337
̸ Long solidus overlay U+0338

Example: H̷e̷l̷l̷o̷ (strikethrough using U+0337 after each letter)

You can stack multiple combining marks on a single base character. Some fonts support extreme stacking, producing text that extends vertically above and below the normal line. The exact visual effect depends heavily on the renderer and font used.

Warning: Excessive use of combining characters can crash some text-rendering engines and make text inaccessible to screen readers and search engines. Use sparingly.


How to Generate Fancy Text

Online Generators

Several websites convert plain text to Unicode fancy text styles:

  • UnicodeFYI Tool — available under /tool/ — converts text to multiple Unicode styles simultaneously and lets you copy individual styles.
  • YayText.com — comprehensive fancy text generator with dozens of styles.
  • LingJam.com — another popular generator, shows all styles at once.
  • TextFancy.com — useful for social media bios and captions.

Typical workflow:

  1. Open a fancy text generator.
  2. Type your text in the input box.
  3. See all Unicode style variants generated in real time.
  4. Click the copy button next to the style you want.
  5. Paste anywhere — the characters are just regular Unicode text.

Python: Converting Text Programmatically

You can map plain ASCII characters to their Unicode mathematical equivalents in code:

BOLD_OFFSET_UPPER = 0x1D400 - 0x41   # A → 𝐀
BOLD_OFFSET_LOWER = 0x1D41A - 0x61   # a → 𝐚

def to_math_bold(text: str) -> str:
    result = []
    for char in text:
        if "A" <= char <= "Z":
            result.append(chr(ord(char) + BOLD_OFFSET_UPPER))
        elif "a" <= char <= "z":
            result.append(chr(ord(char) + BOLD_OFFSET_LOWER))
        else:
            result.append(char)  # Keep as-is (spaces, punctuation, digits)
    return "".join(result)

print(to_math_bold("Hello World"))
# → 𝐇𝐞𝐥𝐥𝐨 𝐖𝐨𝐫𝐥𝐝

The same pattern applies to all mathematical alphanumeric ranges — just change the offset to match the target block. Note that some characters in the mathematical ranges have exceptions: the script H is ℋ (U+210B), the italic h is ℎ (U+210E), and so on. A complete implementation needs to handle these special cases.


Accessibility and Practical Considerations

Because Unicode fancy text characters are not the actual Latin letters A–Z, they create real problems in some contexts.

Screen Readers

A screen reader encountering 𝐇𝐞𝐥𝐥𝐨 does not read "Hello" — it reads the Unicode names of those characters aloud. Depending on the reader and version, you might hear: "MATHEMATICAL BOLD CAPITAL H, MATHEMATICAL BOLD SMALL E, MATHEMATICAL BOLD SMALL L..."

This makes fancy text essentially unreadable for users who rely on assistive technology.

Search Engines

Search engines index content by the actual Unicode characters, not their Latin equivalents. Searching for "Hello" will not find 𝐇𝐞𝐥𝐥𝐨. If SEO matters for your content, fancy text in headings and body copy is counterproductive.

Copy-Paste and Interoperability

When a user copies fancy text into a context that does not support those code points (an older SMS app, a system that only handles ASCII, a database with limited encoding), the text may appear as question marks or boxes.

When Fancy Text Is Appropriate

  • Social media display names and bios where visual impact matters.
  • Decorative headings in creative contexts.
  • Mathematical writing where these characters have their intended semantic meaning (e.g., 𝕍 for a vector space, ℝ for the real numbers).
  • Personal expression in contexts where accessibility is not a concern.

When to Avoid It

  • Body text in web pages (use CSS font-weight, font-style, font-family instead).
  • Email subject lines (email clients may render boxes).
  • Any content that must be findable by search.
  • Any content read by screen reader users.

Unicode fancy text is a powerful creative tool rooted in real mathematical typography. Understanding that these are actual Unicode characters — not fonts — helps you use them intentionally, deploy them where they add value, and avoid the pitfalls that come with characters that look like letters but are classified as symbols.
