OTF generation seems to fail when mixed case glyphs are declared

In a case of trying to extract glyph drawings from a UFO to insert them in one of the PluminJS demos, I stumbled upon an apparent failure in some specific cases.

Generating a font from a subset of lowercase letters works fine, from a to z. But adding only one capital letter to the subset of glyphs is enough make the plugin demo fail silently. Same happens while trying to do the reverse, an all capital set will be generated, but one lowercase in the midst of it will cause the generation to fail.

Here’s the general process I went through: – Open a UFO File in Robofont – have a script generate a proper font and glyph declaration based on the selected glyphs in Robofont – have the same script generate drawing instructions for each glyph – use the PluminJS demo to quickly generate a functioning though incomplete webfont from the few glyphs extracted by Robofont and drawn as plumin.Glyphs.

Thanks Loïc, I'll look into this : )
