I have just done what was needed to make Gill Sans to work with my LaTeX package. It took a lot of misery to get to this point but I'm pleased to have done so.
However, there is a problem when displaying the two letters 'fi' together. Instead it spits out the empty square character. Secondly, the resolution of each character is noticeably words than with the stock fonts.
Is there an explanation for why this is the case? I would be grateful for any suggested solutions.
I have put the files in the relevant directories (including .tfm, .fd and style files) and updated the map file.
Just to clarify, the 'f' and 'i' characters display fine on their own, but only together cause this problem. I have also noticed that quotation marks also give the same result (square character), which makes me think that the problem is cause because Latex can't cope with the small spacings
