Tonic sol-fa gives names to the seven scale degrees then modifies the vowel sound of note names to indicate semitone modifications. It handles enharmonic respellings, so for instance, do di re ri mi is enharmonically equivalent to do ra re me mi
Regular stave notation has symbols for half sharps and three quarter sharps and so on.
Does tonic sol-fa have further modifications of the existing note names to describe quarter tone note names? Or is it 12-tone only?
There are some proposed solutions for a variety of tunings.

In the composer John Lambert's ear-training classes, he got his students to sing quarter-tone exercises using - I think - DIE RYE MY FIE SIGH LIE and TIE for quarter sharps, and DAW TAW LAW SAW FORE MORE and RAW for quarter flats. Although musical grammar also requires three-quarter sharps and three-quarter flats, I don't think they were used.
I never saw these syllables written down so they may not be spelt as he spelt them. (In the UK we really do spell spelled, spelt!) But he did invent a system called 'English solfege', and perhaps if you could track it down...

Apparently there are such systems, but I don't know how much they have been adopted.

But that conflicts with chromatic solfege...
