U03E1

U03E1 is a Unicode code point typically written in the form U+03E1. It resides in the Greek and Coptic block, which spans from U+0370 to U+03FF and is reserved for characters used in classical Greek texts as well as related symbols and diacritics connected to Coptic writing.

The precise character represented by U+03E1 is defined in the Unicode Character Database. The Greek and Coptic block includes a variety of letters, diacritics, and special symbols; the exact identity and naming of U+03E1 depend on the Unicode version and the font being used. In practical terms, the code point may correspond to a Greek letter, a modifier, or another symbol that the standard assigns to that position. To determine the current designation, one should consult the official Unicode charts or the character database for the relevant version.

Encoding and rendering aspects are straightforward in principle. U+03E1 is encoded in UTF-8 as a two-byte sequence and can be represented in text using a hexadecimal or decimal numeric character reference (for example, in HTML or XML, as ϡ or ϡ). Whether a glyph is visible depends on font support; if a font lacks a glyph for U+03E1, rendering systems may substitute a placeholder or fallback character.
