In general, different fonts, different line measures (available space to set a line), different properties (e.g., whether to use letter or word spacing), all contribute to the setting of glyphs in a line. Usually, if no letter spacing and no kerning applies, then a word is set on a glyph by glyph basis according to the applicable font's glyph advancement per glyph (a.k.a. character width per character in some contexts).
However, usually kerning is enabled by default, so one will also get variation within a word, even with no letter spacing. For line breaking and nominal word space calculation (when using justified alignment mode), FOP uses a line breaking algorithm based on Knuth's optimal paragraph breaking found in TeX.
