unicode-charnames 15.0.0

Look up Unicode character name or code point label and search in Unicode character names

unicode-charnames

This package supports Unicode version 15.0, released on September 13, 2022.

The library provides:

• A function to get the character name (the normative character property “Name”) or the code point label (for characters that do not have character names) of a single Unicode character.
• A function to get the code point value (in the usual 4- to 6-digit hexadecimal format) corresponding to a Unicode character name; the search is case-sensitive and requires exact string match.
• A function to search characters by character name; the search is case-insensitive but requires exact substring match.

The generic term “character name” refers to the Unicode character “Name” property value for an encoded Unicode character. For code points that do not have character names (unassigned, reserved code points and other special code point types), the Unicode standard uses constructed Unicode code point labels, displayed between angle brackets, to stand in for character names.

Example usage

    from unicode_charnames import charname, codepoint, search_charnames

    # charname
    for char in '龠💓\u00E5\u0002':
        print(charname(char))
        # Output:

        # 32FF
        # None

    # search_charnames
    for x in search_charnames('break'):
