There's certainly some relationship between font spacing and reflow.

Also, please note that while for ASCII, it's usual to have fixed-width 
fonts, such fonts don't exactly exist for Unicode. There are several 
models that come close to the "fixed width" model of ASCII, such as the 
East Asian full-width/half-width model, but for some scripts (e.g. 
Arabic), any kind of fixed-pitch model is looking highly suboptimal. On 
top of that, there's the issue of character width vs. bytes-per-character.

Of course, we don't expect too much (non-ASCII) Unicode stuff, but being 
able to reflow will help visual quality where we need Unicode, avoiding 
too short or too long lines even after using careful heuristics when 
trying to line-break the text.
