Font Looks Much Different?

Maybe it's a little late, but I will just add some extra info.

I have my own font engine and I tested this font "Viking Younger Runes".

This font has some bad points. This kind of problem is very common in non-professional fonts, since it's easy to forget some garbage when creating glyphs in font editors.

Most bad fonts I have dealt with work on Windows font rasterizer, and some of them have much worse errors than this one. This kind of problem is so usual than some years ago I also needed to code, in my font rasterizer, some algorithms to remove bad data. All times I have debugged a particular problematic font, the bad data were not visible when drawing.

If a program you are using requests a missing font (because it's not there or it couldn't be loaded), most font engines use a default one. In Windows XP, the default font is Arial or MS Sans Serif, depending on some extra factors.

What do you mean by, "bad points"?

Good question. :geek

I didn't debug the font to have a detailed log (it usually takes a long time). I just passed the font through my test programs (as I said, I'm already used to this kind of thing). The program that tests the geometric data (lines and splines) integrity failed.

From my previous debugging sections, the most common errors I already got are:
- shapes with just one point;
- shapes with several points, but all are the same;
- shapes with zero area (just 2 points, or many collinear points);
- splines with unexpected end (missing points);
- glyphs with positive polygons that are inside negative polygons (holes).

If it doesn't make sense for you, never mind. I was just trying to say that the font is guilty, not gimp. :bigthup

I've run into a lot of fonts like that. They work in native Microsoft programs like Word, but in Linux or in software ported to Windows -- PHOOEY. Something wrong with the file structure that Windowsy things don't care about -- or like.
