Description Masa Oshima 2013-11-28 08:07:48 UTC
Description of problem:
  $ LC_MESSAGES=ja_JP.utf8 man xxd
  I got a lot of UTF8 surrogate pair encoding. looks like a garbled page.

  I found when I saw the xxd manpage.
  Same issue occured in vim-common package includs in Japanese locale manpage.
  In other Japanese manpage, it looks like ok (ex. LC_MESSAGES=ja_JP.utf8 man nkf)

Version-Release number of selected component (if applicable):

How reproducible:
  It`s easy, following command below.

Steps to Reproduce:
1. $ LC_MESSAGES=ja_JP.utf8 man xxd
2. $ LC_MESSAGES=ja_JP.utf8 man evim
3. $ LC_MESSAGES=ja_JP.utf8 man vim
4. $ LC_MESSAGES=ja_JP.utf8 man vimdiff
5. $ LC_MESSAGES=ja_JP.utf8 man vimdiff
6. $ LC_MESSAGES=ja_JP.utf8 man vimtutor

(It`s ok example: LC_MESSAGES=ja_JP.utf8 man nkf)

Actual results:
  UTF8 surrogate pair encoding in manpage.

Expected results:
  Japanese character looks like fine.

Additional info:
  Invalid manpage same as below:
  $ zcat /usr/share/man/ja/man1/xxd.1.gz | file -
  /dev/stdin: troff or preprocessor input, UTF-8 Unicode text, with LF, NEL line terminators

  Valid manpage same as below:
  $ zcat /usr/share/man/ja/man1/nkf.1.gz | file -
  /dev/stdin: troff or preprocessor input, UTF-8 Unicode text

I AM sorry my dirrty english.

Anybody else?

Comment 2 Noriko Mizumoto 2013-12-01 22:12:20 UTC

Thank you for filing a bug.
This project is not part of Fedora Project its self, but is one of upstream project for Fedora distributions. It seems that this project owns their separate localization team, and it is best to contact them for any bug.

Comment 3 Masa Oshima 2013-12-02 02:53:25 UTC
Thanks Noriko-san.

I intend to contact the their vim-jp team.


Comment 4 Masa Oshima 2013-12-09 12:53:19 UTC
Re-open request.

Because I cannot illustrate by English, I illustrate by a native language.


時間をみつけて再調査しました。その結果、vim.spec の修正が必要だとの結論に至りました。

vim.spec の494-497行目の辺りで 元からあるファイルをlatin1 -> UTF8 変換しています。
ここの処理の対象になっている日本語以外の他の自然言語(フランス語,イタリア語,ポーランド語,ロシア語 処理順)では

LANG=fr_FR.utf8 man vim
LANG=it_IT.utf8 man vim
LANG=pl_PL.utf8 man vim
LANG=ru_RU.utf8 man vim

rpmbuild with modified vim.spec logs

This log is a part of "rpmbuild -bb vim.spec", vim.spec was a modified by my hand. Add file command.

In French, Italian, Polish, Russian:
From ISO-8859 text to UTF-8 Unicode text By "iconv -f latin1 -t UTF8 blar", works fine.

In Japanese:
From UTF-8 Unicode text to TF-8 Unicode text By "iconv -f latin1 -t UTF8 blar", got garbled.

Comment 7 Noriko Mizumoto 2013-12-11 01:03:49 UTC

It is now identified that this bug is specific to Fedora, and that the cause is in vim.spec (line#494-497). The lines in question work fine with French, Italian, Polish and Russian (as latin1), but those do not work for Japanese (as utf8). It needs the package maintainer's attention and fix.
Please see the attachments above.

Now this bug is reset it's product and component to 'Fedora' and 'vim'.

A patch for current newest vesion vim.spec 7.4.131-1

I added 'file' command for iconv don`t needed in UTF-8 manpage.
So now new depend on 'file' command in vim-common package.
Master Karsten, could you please accept this humble pull-request ?

This bug appears to have been reported against 'rawhide' during the Fedora 22 development cycle.
Changing version to '22'.
