Atlas repeated unknown character

[Quetzalfir]

I can notice that in the demo distance-field.c, if I set some new characters that are not representable, there are multiple box repeated in the atlas, does this happens only in the demo as a way of representing the unknown character?, or the library does save the glyph repeatedly?

in the case it saves memory, how can I create an atlas with the unknown glyphs pointing to the same region of the atlas?, avoiding the repeating situation.

They are not supposed to be here and means the demo failed at getting the proper glyph. What is the font ?

[Quetzalfir]

it's the same one that is in the demo "Vera.ttf". I just added some new extended ascii characters to it. It seems that cannot represent all of the characters, so it put the same box repeatedly

IF those glyphs are present within the font, it's probably a bad access to the charcode (I may use directly the letter code while you need an indirection through a freetype function). Can you check other demos to check if the problem is also present?
