Full_Name: YAMAGUCHI Shingo
Version: snapshot 20020531, snapshot 20020602
CVS_Date:
OS: Linux 2.4.18 (glibc 2.2.5, gcc 3.1)
X_Server: XFree86 4.2.99.1
Submission from: (NULL) (210.128.199.160)
If LC_CTYPE is undefined, FvwmForm cannot display any multibyte (I use
EUC-JP) character (If LC_CTYPE set to "ja_JP.eucJP", FvwmForm works fine).
FlocaleInit() in FvwmForm main() is this:
FlocaleInit(LC_CTYPE, getenv("LC_CTYPE"), "", "FvwmForm");
If "LC_CTYPE" environment variable is undefined, getenv() returns NULL
pointer. And NULL pointer is sent to setlocale() in FlocaleInit(). If
setlocale() receive NULL pointer locale argument, return value is
undefined.
Instead of using getenv(), use "empty string". i.e.:
FlocaleInit(LC_CTYPE, "", "", "FvwmForm");
This means "Use default locale which is selected from one of the
environment variables (LC_*, LANG)". This technique is used on FvwmPager
etc.
