Environment

Microsoft Windows 2000/XP Japanese version

Description

Japanese (and Chinese, Korean) language has over 30,000 characters.
To use our language on computers, 8bit ascii character sets are not sufficient.
We use double-byte character sets for file names etc..
On double-byte character sets environment, many characters consists of 16bits(=double-byte).

In Japan the most major character set is called Shift-JIS (Japanese Industrial Standards) which is used on MS Windows.
And on Shift-JIS environment some characters have '0x5c' for the second byte. It conflicts with backslash on 8bit ascii code.

So when I use original gnupg on Japanese MS Windows, I sometimes meet errors on finding gnupg configuration files.

How To Repeat

On Japanse MS Windows Environment, put gnupg conf files into a directory which name contains double-byte character whose seconde byte is '0x5c'.
Then execute gpg.exe with '--homedir=' option.

Fix

I made a patch for gnupg-1.4.2 but I don't know if this meets gnupg developers' policy.
Please consider what I want to indicate.
