Or you could go back to the old Algol idea of underlining keywords.
Both have the same problem, though: They make editing with an ordinary
text editor pretty much impossible. You need a language-aware IDE which
makes entering these characters or markups simple. Maybe even a
specialized keyboard like they had for APL (or the Sinclair ZX computers
which had special combinations for all the BASIC keywords). And if you
go this way, why not go a step further and dissociate the program from
its linear text representation? Add footnotes, different views,
hyperlinks, format mathematical expressions like formulas, etc.
