New Comment:
Take a look at bug #26901. I summerized the
"rectangular / square placeholders" issues that you may
encounter when using non-ASCII characters with
ImageTTFText() / ImageFTText().

I'll take a look into this.
Assign to myself.

Additional info:
I talked again to the freetype guys.
They asked me to try to use "" instead of the characters. This
worked fine:
<quote>
If  works but UTF-8 not then GD was compiled with the option
JISX0208 which IMHO prevents decoding of UTF-8 encoded character
codes.
Then try to find out why this option was set.

Being the lazy asses we are, could you add some
short example script which shows what doesn't work?

Hello,
I want to output the webdings.ttf font using freetype and gd.
Unfortunately I only get rectangular symbols back.
I discusse the issue inside the freetype mailing list and they told me
that
"FreeType2 selects a Unicode charmap as default charmap for a font if
available. Webdings.ttf does not have a Unicode charmap."
They thought that it could be a bug in gd and supplied a patch for
gdlib.

for (n = 0; n < a->face->num_charmaps; n++)
{
charmap = a->face->charmaps[n];
platform = charmap->platform_id;
encoding = charmap->encoding_id;
if ((platform == 3 && encoding == 1) /* Windows Unicode */
|| (platform == 3 && encoding == 0) /* Windows Symbol */
|| (platform == 2 && encoding == 1) /* ISO Unicode */
|| (platform == 0))
{ /* Apple Unicode */
a->have_char_map_unicode = 1;
found = charmap;
----8<----
So it would work if GD would not forget to tell FreeType2 to use the
charmap it found... :

I applied it, but it still doesn't seem to work.
I'm sure that the right gd is linked (ldd).
I've seen examples with Zapf Dingbats and Webdings work with other
languages, so I think it may be also a php issue.
Maybe you could point me on a solution.
Thanks in advance
