crash when user name has Japanese-Katakana characters

[Nobuto Murata]

When user name of Windows has Japanese Katakana Characters,
Wubi crashes immediately without any log files.

http://en.wikipedia.org/wiki/Katakana
Windows version: Windows 7 Home Premium (Japanese)

How to reproduce:
1. Boot Windows with a user name has Japanese Katakana Characters.
2. Insert Ubuntu 9.10 CD.
3. Execute Wubi
4. Wubi crashes

Expected result:
4. Wubi launch and success install.

How to avoid this issue temporarily:
1. Make "temp" folder beneath C: drive.
2. Execute Wubi.
3. Success install.
4. You get a log file in C:\temp.

Above is the log with user name "テストアカウント" after making C:\temp folder.

I do not see any error in the log above, it seems like the installation was completed.

I think the problem is not about Katakana characters but that you didn't have ANY temp directory.
Wubi extracts its files to the temp directory, which in this case becomes impossible.

[Agostino Russo (ago)]

The vast majority of windows users should have a temp directory available by default (user or system), we could extract files to memory but that is a bit invasive and I do not feel we need to change things unless there are more user cases. Also because the workaround (creating a temp directory) should be fairly straightforward.

Yes it's the log file when installation complete.
Making C:\temp works fine.
But usually we don't have C:\temp folder.

Temp directory exists as "C:\Users\テスト~1\AppData\Local\Temp\".
This directory is used by Wubi like "C:\Users\テスト~1\AppData\Local\Temp\pyl435B.tmp\data".
I think the log file shows this fact.
But only log file is stored like c:\temp\wubi-9.10ubuntu1-rev160.log.

I see,

I think the c++ side has problems accessing the user temp directory, so it fails if there is no system temp directory.

Without c:\temp, what is the output of

echo %temp%

? Does it point to your user temp dir?

[Nobuto Murata (nobuto)]

echo %temp%
returns
C:\Users\テスト~1\AppData\Local\Temp

It came from windows configurations "%USERPROFILE%\AppData\Local\Temp".
