- fontTools.unicodedata.category(chr, /)
Returns the general category assigned to the character chr as string.
- fontTools.unicodedata.bidirectional(chr, /)
Returns the bidirectional class assigned to the character chr as string.
If no such value is defined, an empty string is returned.

Returns the east asian width assigned to the character chr as string.
- fontTools.unicodedata.mirrored(chr, /)
Returns the mirrored property assigned to the character chr as integer.
Returns 1 if the character has been identified as a “mirrored” character in bidirectional text, 0 otherwise.
- fontTools.unicodedata.decomposition(chr, /)
Returns the character decomposition mapping assigned to the character chr as string.
An empty string is returned in case no such mapping is defined.
- fontTools.unicodedata.normalize(form, unistr, /)
Return the normal form ‘form’ for the Unicode string unistr.
Valid values for form are ‘NFC’, ‘NFKC’, ‘NFD’, and ‘NFKD’.
- fontTools.unicodedata.block(char)[source]
Return the block property assigned to the Unicode character ‘char’ as a string.
>>> block("a") 'Basic Latin' >>> block(chr(0x060C)) 'Arabic' >>> block(chr(0xEFFFF)) 'No_Block'
- fontTools.unicodedata.script(char)[source]
Return the four-letter script code assigned to the Unicode character ‘char’ as string.
>>> script("a") 'Latn' >>> script(",") 'Zyyy' >>> script(chr(0x10FFFF)) 'Zzzz'
- fontTools.unicodedata.script_extension(char)[source]
Return the script extension property assigned to the Unicode character ‘char’ as a set of string.
>>> script_extension("a") == {'Latn'} True >>> script_extension(chr(0x060C)) == {'Nkoo', 'Arab', 'Rohg', 'Thaa', 'Syrc', 'Gara', 'Yezi'} True >>> script_extension(chr(0x10FFFF)) == {'Zzzz'} True
- fontTools.unicodedata.script_name(code, default=<class 'KeyError'>)[source]
Return the long, human-readable script name given a four-letter Unicode script code.
If no matching name is found, a KeyError is raised by default.
You can use the ‘default’ argument to return a fallback value (e.g. ‘Unknown’ or None) instead of throwing an error.
- fontTools.unicodedata.script_code(script_name, default=<class 'KeyError'>)[source]
Returns the four-letter Unicode script code from its long name
If no matching script code is found, a KeyError is raised by default.
You can use the ‘default’ argument to return a fallback string (e.g. ‘Zzzz’ or None) instead of throwing an error.
- fontTools.unicodedata.script_horizontal_direction(script_code: str, default: T) Literal['RTL', 'LTR'] | T[source]
- fontTools.unicodedata.script_horizontal_direction(script_code: str, default: type[KeyError] = KeyError) Literal['RTL', 'LTR']
Return “RTL” for scripts that contain right-to-left characters according to the Bidi_Class property. Otherwise return “LTR”.
