EVALUATION See (a last) suggested fix. There's bug in XlibWrapper.c implementation of SetProperty wrapper. In a certain loop, we must calculate length in bytes, not characters. ###@###.### 2005-06-21 12:22:13 GMT Oops, buggy part was already fixed with 6269884. ###@###.### 2005-06-22 07:31:19 GMT

SUGGESTED FIX (see update below) This bug supposedly can be fixed for most window managers and Linux distributions by the following patch. After the fix, I cannot reproduce this bug any more on my available machines. Note however, that I always set locale to a standard name from supported by X11 list of charsets, but not necessary UTF-8. ------- XlibWrapper.c ------- *** /tmp/sccs.3bZxsz 2005-02-15 17:18:24.511360586 +0300 --- XlibWrapper.c 2005-02-15 17:17:14.977590885 +0300 *************** *** 620,626 **** } #ifdef X_HAVE_UTF8_STRING status = Xutf8TextListToTextProperty((Display *)jlong_to_ptr(display), &cname, 1, ! XStdICCTextStyle, &tp); #else status = XmbTextListToTextProperty((Display *)jlong_to_ptr(display), &cname, 1, XStdICCTextStyle, &tp); --- 620,626 ---- } #ifdef X_HAVE_UTF8_STRING status = Xutf8TextListToTextProperty((Display *)jlong_to_ptr(display), &cname, 1, ! XUTF8StringStyle, &tp); #else status = XmbTextListToTextProperty((Display *)jlong_to_ptr(display), &cname, 1, XStdICCTextStyle, &tp); ###@###.### 2005-2-15 14:23:30 GMT UPDATE In fact, there was a bug in a loop after line 658. After this fix below, code should work locale-independent. ------- XlibWrapper.c ------- *** /tmp/sccs.Ox3Ewg 2005-06-21 16:15:38.844564588 +0400 --- XlibWrapper.c 2005-06-21 16:14:02.655604799 +0400 *************** *** 658,664 **** --- 658,668 ---- cname = ""; } + #ifdef X_HAVE_UTF8_STRING + length = (*env)->GetStringUTFLength(env, jstr); + #else length = (*env)->GetStringLength(env, jstr); + #endif list = malloc(length * sizeof(char*)); // Definitely not bigger than this list_ptr = list; *************** *** 677,683 **** #ifdef X_HAVE_UTF8_STRING status = Xutf8TextListToTextProperty((Display *)jlong_to_ptr(display), list, count, !

WORK AROUND Use a ja_JP.utf8 (or equivalent) locale. ###@###.### 2005-2-09 17:16:07 GMT
