tracking

Hello. I'm designing a font intended to be used mainly as a subtitle font. It's a sans-serif font not unlike Helvetica.

The em size is 2000 (I know it "should" be 2048 for a truetype font), the ascent/descent are 1600/400. Most glyphs don't go higher than 1450 though, with the exception of accented Latin characters.

There lies the issue: when my font includes accented Latin characters, the tracking (line -of-text intradistance, but correct me if I got the term "tracking" wrong) skyrockets. I can't seem to find a way to control that.

As my intended design goes, I don't mind if I have a descender (e.g. "g") above and an accented capital Latin letter below and they almost touch. It's something that does not happen very often, anyway.

How can I control tracking? It seems it's auto-calculated.
