| lookup(name) | Look up a Unicode character by name. | unicodedata.lookup('SOLIDUS') # returns '/' |
| name(unichr[, default]) | Returns the name assigned to the Unicode character, or default if the character does not exist. | unicodedata.name(u'/') # returns 'SOLIDUS' |
| decimal(unichr[, default]) | Returns the decimal value assigned to the Unicode character, or default if no decimal value is defined. | unichr = unicodedata.lookup('DIGIT FOUR') num = unicodedata.decimal(unichr) # returns 4 |
| numeric(unichr[, default]) | Returns the numeric value assigned to the Unicode character (as a floating point number), or default if no numeric value is defined. | unichr = unicodedata.lookup('DIGIT FOUR') num = unicodedata.digit(unichr) # returns 4.0 |
| category(unichr) | Returns the general category of the Unicode character. | unicodedata.category(u'/') # returns 'Po' |
