Unicode Database
================

Access the Unicode Database.  This module was written by Marc-Andre
Lemburg <mal@lemburg.com>.
This manual section was written by Marc-Andre Lemburg <mal@lemburg.com>.
This module provides access to the Unicode Character Database which
defines character properties for all Unicode characters. The data in
this database is based on the `UnicodeData.txt' file version 3.0.0
which is publically available from <ftp://ftp.unicode.org/>.

The module uses the same names and symbols as defined by the
UnicodeData File Format 3.0.0 (see
<http://www.unicode.org/Public/UNIDATA/UnicodeData.html>).  It defines
the following functions:

`lookup(name)'
     Look up character by name.  If a character with the given name is
     found, return the corresponding Unicode character.  If not found,
     `KeyError' is raised.

`name(unichr[, default])'
     Returns the name assigned to the Unicode character UNICHR as a
     string. If no name is defined, DEFAULT is returned, or, if not
     given, `ValueError' is raised.

`decimal(unichr[, default])'
     Returns the decimal value assigned to the Unicode character UNICHR
     as integer. If no such value is defined, DEFAULT is returned, or,
     if not given, `ValueError' is raised.

`digit(unichr[, default])'
     Returns the digit value assigned to the Unicode character UNICHR
     as integer. If no such value is defined, DEFAULT is returned, or,
     if not given, `ValueError' is raised.

`numeric(unichr[, default])'
     Returns the numeric value assigned to the Unicode character UNICHR
     as float. If no such value is defined, DEFAULT is returned, or, if
     not given, `ValueError' is raised.

`category(unichr)'
     Returns the general category assigned to the Unicode character
     UNICHR as string.

`bidirectional(unichr)'
     Returns the bidirectional category assigned to the Unicode
     character UNICHR as string. If no such value is defined, an empty
     string is returned.

`combining(unichr)'
     Returns the canonical combining class assigned to the Unicode
     character UNICHR as integer. Returns `0' if no combining class is
     defined.

`mirrored(unichr)'
     Returns the mirrored property of assigned to the Unicode character
     UNICHR as integer. Returns `1' if the character has been
     identified as a "mirrored" character in bidirectional text, `0'
     otherwise.

`decomposition(unichr)'
     Returns the character decomposition mapping assigned to the Unicode
     character UNICHR as string. An empty string is returned in case no
     such mapping is defined.
