Yes. This bug also occurs on many Japanese users' Linux/Windows environment.
(Many Japanese users have talked about this bug on a certain Japanese BBS
 where they chat,
 but it seems that they have not yet reported it to this list... X-(
 I intended to investigate and report it when I have some time but couldn't.
 Sorry for having failed to report my knowledge, and thank you, Onken.)

When we write a log in Japanese and run 'svn log', the log is displayed
However, when we display the log with 'svnlook log', each multi-byte
character in it turns into two '?\nnn' (n is a number) such as:
  ?\179?\171?\187?\207?\164?\222?\164?\199 3 ?\187?\254?\180?\214?\164?\219

I hear this bug does not occur on Fedora Core, which use a UTF8 character
encoding system.
I also hear that this bug has been existing since the period of Subversion
0.37 (at the latest).

This bug is different from #1997 because displayed characters are '?\nnn',
not raw UTF8 characters.
But I attribute it to character recoding alike.

I've mentioned all I know.
