I am using a font called SANS in TITLE 3D in BORIS (2.1.0.060120) in FCP 6.
When I use the light or extra light font everything looks fine, but when I go to Plain or Bold, large spaces appear between the words. Adjusting tracking or kerning globally does not really help as the letters in the words get crammed together but the spaces between the words are proportionally still too large.
There is an individual fix which is to select the last letter of a word and the first letter of the next one and then adjust the kerning. This works perfectly, but is very time consuming for a long text.
