Convert-EastAsianWidth (0.10)

As the module stands, it doesn't do what it claims to do. The parts of the module which work are the ones concerning full/halfwidth ascii and punctuation characters.

Guess what though? You can just use tr/// to convert full/halfwidth ascii, as follows:

$input =~ tr/\x{3000}\x{FF01}-\x{FF5E}/ -~/;
$input =~ tr/ -~/\x{3000}\x{FF01}-\x{FF5E}/;

The same method will work for punctuation characters too, and I think it's much quicker than this module's method of going via "charnames".

However, the conversion of full/half width katakana is a slightly more complicated problem because of the need to incorporate diacritics, and this module unfortunately doesn't handle that problem at all.
