Unicode::EastAsianWidth provide user-defined Unicode properties that deal with
|
|
width status of East Asian characters, as specified in
|
|
http://www.unicode.org/unicode/reports/tr11/.
|
|
|
|
It exports the following functions to the caller's scope, to be used by Perl's
|
|
Unicode matching system: InEastAsianFullwidth, InEastAsianHalfwidth,
|
|
InEastAsianAmbiguous, InEastAsianNarrow InEastAsianWide, InEastAsianNeutral.
|
|
|
|
In accord to TR11 cited above, two additional context-sensitive properties are
|
|
exported: InFullwidth (union of Fullwidth and Wide) and InHalfwidth (union of
|
|
Halfwidth, Narrow and Neutral).
|
|
|
|
Ambiguous characters are treated by default as part of InHalfwidth, but you can
|
|
modify this behaviour by assigning a true value to
|
|
$Unicode::EastAsianWidth::EastAsian at compile time within a BEGIN block before
|
|
loading this module
