How to Distinguish
These characters may look similar but belong to different scripts and blocks. LATIN CAPITAL LETTER I is from the Basic Latin block (Latn script), while GREEK CAPITAL LETTER IOTA is from Greek and Coptic (Grek). Check the codepoint or encoding to tell them apart.
Tip: Paste the character into a hex editor or use
charCodeAt()
in JavaScript to check the actual codepoint.
