0x03E1

0x03E1 is the hexadecimal notation used to refer to the Unicode code point U+03E1. It sits in the Greek and Coptic block of the Unicode standard and is associated with an archaic Greek character.

The character represented by U+03E1 is commonly named GREEK SMALL LETTER SAMPI. Sampi is an ancient Greek letter that appeared in some early alphabets and also functioned as a numeral symbol in certain regional variants. In scholarly editions and digital texts of ancient Greek, sampi may be encountered as part of historical scripts or numeral systems, though it is not used in contemporary Greek orthography.

In modern computing, U+03E1 is encoded as a single Unicode scalar value. When stored or transmitted, its representation depends on the chosen text encoding (for example UTF-8 or UTF-16). Rendering of the sampi depends on font support; many standard fonts do not include it, while specialized fonts used by linguists and classicists provide a glyph.

The entry of U+03E1 in Unicode helps enable accurate digital representation of ancient Greek materials. It is one of several archaic or dialectal characters in the same region of the code chart that scholars use when transcribing inscriptions, papyri, and other historical sources. For readers and editors, recognizing sampi and related characters aids in interpretation of numerals and textual variants in ancient Greek studies.
