This utf business is a little tricky. For example, if you use
g_locale_to_utf8 but your locale is not set right (not uncommon) the
function won't work as you expect since it will not obtain a valide
codeset to do the translation. Here is a small wrapper program I use you
might find handy. The locale-defined codeset can be overridden by the
environment variable SMB_CODESET:
gchar *my_utf_string(char *t)
{
static gchar *s = NULL;
GError *error = NULL;
gsize r_bytes, w_bytes;
unsigned char *c;
const char *fc;
gchar *from_codeset=NULL;
if(!t) g_assert_not_reached();
if (g_utf8_validate (t,-1,NULL)) return t;
/* so we got a non-UTF-8 */
if (getenv("SMB_CODESET") && strlen( getenv("SMB_CODESET"))){
from_codeset=g_strdup(getenv("SMB_CODESET"));
}
else {
g_get_charset(&fc);
if (fc) from_codeset = g_strdup(fc);
else from_codeset = g_strdup("ISO-8859-1");
}
if (!strcmp(from_codeset,"ISO-")){
g_free(from_codeset);
from_codeset = g_strdup("ISO-8859-1");
}
if(s) g_free(s);
for(c = (unsigned char *)t; *c != 0; c++)
if(*c < 32 && *c != '\n')
*c = ' ';
s = g_convert (t,strlen(t),"UTF-8",from_codeset,&r_bytes, &w_bytes,
&error);
g_free(from_codeset);
if(!s)
{
s=g_strdup(t);
for(c = s; *c != 0; c++) if(*c > 128) *c = '?';
}
if(error){
printf("DBG: %s. Codeset for system is: %s\n",
error->message,from_codeset);
printf("DBG: You should set the environment variable SMB_CODESET
to ISO-8859-1\n");
g_error_free(error);
}
return s;
}
