Hi,


I can see the followings added in fribidi (according to
fribidi-char-sets-list.h)

#ifdef _FRIBIDI_ADD_CHAR_SET_OTHERS
_FRIBIDI_ADD_CHAR_SET_OTHERS (UTF8, utf8)        /* UTF-8 (Unicode) */
_FRIBIDI_ADD_CHAR_SET_OTHERS (CAP_RTL, cap_rtl)        /* CapRTL (Test) */
#endif /* _FRIBIDI_ADD_CHAR_SET_OTHERS */
#ifdef _FRIBIDI_ADD_CHAR_SET_ONE2ONE
_FRIBIDI_ADD_CHAR_SET_ONE2ONE (ISO8859_6, iso8859_6)    /* ISO8859-6
(Arabic) */
_FRIBIDI_ADD_CHAR_SET_ONE2ONE (ISO8859_8, iso8859_8)    /* ISO8859-8
(Hebrew) */
_FRIBIDI_ADD_CHAR_SET_ONE2ONE (CP1255, cp1255)        /* CP1255 (MS
Hebrew/Yiddish) */
_FRIBIDI_ADD_CHAR_SET_ONE2ONE (CP1256, cp1256)        /* CP1256 (MS Arabic)
*/
#endif /* _FRIBIDI_ADD_CHAR_SET_ONE2ONE */


As far as I can see this takes precedence over iconv when fribidi is
compiled in, unless you specify FRIBIDI_NO_CHARSETS when compiling
mapserver. In the latter case iconv is used to when doing the encoding.

The iconv.dll and fribidi.dll should be available to load by the application
by default.
Does this issue exists only when fribidi is compiled in? I can see a couple
of non-const static variables used by the fribidi library and I wonder if we
should protect the access to these functions with locks inside the mapserver
code in a multi-threaded  environment.

Best regards,
