[PATCH v2] localedata: Updates for Taiwanese locales [BZ #24409]

[Wei-Lun Chao]

Hello,

First, alt_digits works like "alt_numbers". I don't know how to just
map each digit to another character.
Before this patch, alt_digits covers 0..31, and this patch covers
0..59. I am not sure, is it worthy to extend
to 0..99, because those presentations are not suitable for year
numbers. For example:
$ LANG=lzh_TW date -d "1959-04-01 09:00:00" +"%Oy<U5E74>"
We will expect <U4E94><U4E5D><U5E74> instead of <U4E94><U5341><U4E5D><U5E74>

Regards,
Wei-Lun CHAO
