|
|
|
|
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 \file{UnicodeData.txt} file version
|
|
3.0.0 which is publically available from \url{ftp://ftp.unicode.org/}.
|
|
|
|
The module uses the same names and symbols as defined by the
|
|
UnicodeData File Format 3.0.0 (see
|
|
\url{http://www.unicode.org/Public/UNIDATA/UnicodeData.html}). It
|
|
defines the following functions:
|
|
|
|
\begin{funcdesc}{lookup}{name}
|
|
Look up character by name. If a character with the
|
|
given name is found, return the corresponding Unicode
|
|
character. If not found, \exception{KeyError} is raised.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{name}{unichr\optional{, default}}
|
|
Returns the name assigned to the Unicode character
|
|
\var{unichr} as a string. If no name is defined,
|
|
\var{default} is returned, or, if not given,
|
|
\exception{ValueError} is raised.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{decimal}{unichr\optional{, default}}
|
|
Returns the decimal value assigned to the Unicode character
|
|
\var{unichr} as integer. If no such value is defined,
|
|
\var{default} is returned, or, if not given,
|
|
\exception{ValueError} is raised.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{digit}{unichr\optional{, default}}
|
|
Returns the digit value assigned to the Unicode character
|
|
\var{unichr} as integer. If no such value is defined,
|
|
\var{default} is returned, or, if not given,
|
|
\exception{ValueError} is raised.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{numeric}{unichr\optional{, default}}
|
|
Returns the numeric value assigned to the Unicode character
|
|
\var{unichr} as float. If no such value is defined, \var{default} is
|
|
returned, or, if not given, \exception{ValueError} is raised.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{category}{unichr}
|
|
Returns the general category assigned to the Unicode character
|
|
\var{unichr} as string.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{bidirectional}{unichr}
|
|
Returns the bidirectional category assigned to the Unicode character
|
|
\var{unichr} as string. If no such value is defined, an empty string
|
|
is returned.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{combining}{unichr}
|
|
Returns the canonical combining class assigned to the Unicode
|
|
character \var{unichr} as integer. Returns \code{0} if no combining
|
|
class is defined.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{mirrored}{unichr}
|
|
Returns the mirrored property of assigned to the Unicode character
|
|
\var{unichr} as integer. Returns \code{1} if the character has been
|
|
identified as a ``mirrored'' character in bidirectional text,
|
|
\code{0} otherwise.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{decomposition}{unichr}
|
|
Returns the character decomposition mapping assigned to the Unicode
|
|
character \var{unichr} as string. An empty string is returned in case
|
|
no such mapping is defined.
|
|
\end{funcdesc}
