I was thinking about removing () from the translated strings, but decided
against it since there are a lot of full-width parenthesis in the translated
strings already:
$ cd po; git grep -B 1 'msgstr.*（'
... 246 matches in zh_CN ...
and it seems strange to force only a few pairs of parens to be half-width to
make the code simpler. I don't know if that's a great argument, since it is
somewhat aesthetic. I would have liked half-width parens more if it were
closing off purely ASCII text. But it is in fact surrounding Chinese text:
