Hi there 
I downloaded a copy of the font Bpmono but it doesn’t have the latin chars I need(aacute, eacute, iacute, ccedilla…).
So I thought I could modify the font for my personal use, adding these chars.
But I’m having trouble using the font. If I just use Bpmono, it works fine. But when I try to use the modified version, my code editor crashes.
After some tests, I decided just to save the font without modifying it. Open the original, save it, install it. The problem remains.
Any thoughts? 8D
It seems to be a monospaced font. Maybe you added some glyphs that were not 600 funits wide?
Indeed, it is a monospaced font. But like I said, only by saving it(without changing anything), the font becomes damaged.
And when I was adding the glyphs, I copied and pasted the letters and then added the accents, so I don’t think it is a metric problem.
After I was done, I ran a validation check and fixed the problems FontCreator detected - problem which the font already had.
Thank your for your response, anyway.
