examples of extended unicode that does show up in site thumbnails:

All unicode glyphs (that I've seen so far) are displayed on the YTMNDs themselves.

I just found a couple sites with empty characters in thumbnails that have an additional glitch where the site itself won't display anything but the background color...

I spent a good deal of time looking into this. First I tried a new version of the tahoma.ttf (which is 700k as opposed to the current file we're using at 300k). I made sure I was sending everything to GD as UTF-8, and I even tried decimal-escaping the text. I've been using the five sites above as a test and it looks like the issue is with freetype,

These don't work:

string(8) "〠"
string(7) "☪"
string(7) "☼"

These do work:

string(6) "İ"
string(7) "ڱ"

It looks like the extended unicode set just doesn't work on GD's imageTTFText. I wonder if i could use something else to generate this stuff.

I'm putting this on hold for now until YTMND 2.1 isn't so pressing.

Thanks, this is something I never would have paid attention to unless someone had brought it up first.
