adding accented glyphs to an existing font

[thomas]

I have just purchased type 3.2 in order to edit a font (and I am totally new to font design)...
The original font is great but it is missing the accented characters for foreign languages...
So I load the original font in Type 3.2 and I design my missing characters (by copying and pasting existing elements only).
I save as a .ttf or as an .otf file but the font I obtain is more spaced (kerning?) than the orignial one... Now I could have made a mistake during the editing but here is the thing I don't get:
Even if simply open the original font and save it under a different name without any editing at all, I obtain a font with a different spacing between glyphs...
I attach a screenshot of the preview of the original font (below) and the result font (above).
Any help would be greatly appreciated
Thank you,
Thomas

"Even if simply open the original font and save it under a different name without any editing at all, I obtain a font with a different spacing between glyphs.." This tells me that there is something odd going on - there may be something non-standard about the original font.

Do you want to send me the original font so I can have a look at it ([e-mail])?

A flag in the PostScript table of this font was incorrectly set - indicating that it was a mono-spaced font.

The solution was to open the font in Type 3.2, then select description from the font menu and un-check the mono spaced check-box.
