What I've tended to do in this sort of situation is insert a "Zero Width
Word Joiner" character (it's U+200D, see General Punctuation in
`gucharmap`) into my text where I want to inhibit breaks happening
mid-word when line wrapping is happening.

[the one that gets me is function(args) getting split before the '('
character, so I stream out f u n c t i o n ZWJ ( a r g s ) or so]

For me this is Pango rendering via Cairo to PDF, so I'm not worrying
about this messing up offsets in an GtkTextView editor. I haven't found
a good way to handle that.
