The latter is (ASCII is the subset of Unicode, and Unicode charmap is
default in FT), so basically you don't have to worry about anything.
If you had to deal with some Unicode encoded string (like UTF8), then
you would have to extract each charcode/code point at first.
If by spacing you mean advancing from one character to another, then
yes as well.
Yet with text alignment you will have to deal by yourself or use some
other library.
