If a character with the given name is found, return the corresponding character. If not found, KeyError is raised. For example The characters returned by this function are the same as those produced by \N escape sequence in string literals. For example Returns the name assigned to the character chr as a string. If no name is defined, default is returned, or, if not given, ValueError is raised. For example Returns the decimal value assigned to the character chr as integer. If no such value is defined, default is returned, or, if not given, ValueError is raised. For example Returns the digit value assigned to the character chr as integer. If no such value is defined, default is returned, or, if not given, ValueError is raised Returns the numeric value assigned to the character chr as float. If no such value is defined, default is returned, or, if not given, ValueError is raised Returns the general category assigned to the character chr as string. General category names consist of two letters. See the General Category Values section of the Unicode Character Database documentation < for a list of category codes. For example Returns the bidirectional class assigned to the character chr as string. If no such value is defined, an empty string is returned. See the Bidirectional Class Values section of the Unicode Character Database < documentation for a list of bidirectional codes. For example Returns the canonical combining class assigned to the character chr as integer. Returns 0 if no combining class is defined. See the Canonical Combining Class Values section of the Unicode Character Database < for more information. Returns the east asian width assigned to the character chr as string. For a list of widths and or more information, see the Unicode Standard Annex #11 < Returns the block < assigned to the character chr. For example 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.
