Thanks! After google-ing, i also think it’s an default kerning installed in the font. So we must trust the font-maker ;)
And Michele, thats correct, only it isnt what i was looking for… Cause i want to know if 100% = 1/m or is it 2/m, 3/m and ect.
But than again; i also believe what Ari said. It is a default installed by the font-maker and if i want to know what that is, i should open the font in fontlab or something like that to find out what the font settings are, but i won’t go so far ;).
Now i measured the space within indesign with a line ;)
