Re: [opensuse-m17n] Man page can't display correct chinese locale

Thanks Mike, as the information does help a lot.

Formatting is one of the big I18N issue because I have seem a lot in HP, Solaris and AIX; but not supporting it is another issue.

All Unix support all encodings in Chinese and Japanese, even in groff.

SUNWdoc version 11.10.0 supports both japanese and chinese encodings.

I wonder if there is a way to transport the codes to Linux

Thanks!

What version of SuSE Linux were you using? openSUSE 10.3? Peng Wu (CC:) and me have recently added some more hacks to groff-1.18.1.1 and man-2.4.3 which make it work for Chinese man-pages. Maybe you would like to test that? You can get the improved groff package from http://software.opensuse.org/download/M17N/ for the distributions SUSE_Factory, SUSE_Linux_10.0, SUSE_Linux_10.1, and openSUSE_10.2. I can build an improved "man" rpm for you as well if you tell me which distribution you are using.

I am having issues displaying Chinese manpage with encodings: UTF-8, GB2312 and GB18030 when using nroff -man

When I vi it, I can see the encoding fine, but by using nroff -man, all I see is garble.

groff-1.18.1.1 which we currently have in openSUSE 10.3 doesn't support any multibyte encodings *except* the Japanese encoding EUC-JP. It supports EUC-JP only because it contains a patch to support Japanese which is also used in Debian.

This patch is not in the upstream groff though and it doesn't make much sense to include that patch upstream because this patch is not generic and only helps for Japanese.

The latest version of upstream groff already has some support for UTF-8 though. But that alone doesn't imply that Japanese and Chinese is supported, to support Japanese and Chinese properly, not only support for a suitable encoding is required but also special formatting support (Japanese and Chinese don't have spaces between words, therefore you need different line breaking rules than in English). As far as I know, the latest upstream groff doesn't support proper formatting for Chinese and Japanese yet.

I'll check out the latest groff again and see whether it makes sense to update.
