As person who wrote ‘fill-single-char-nobreak-p’ I can say that its
intention was to work for Polish and Czech typography.  In other words,
what Marcin reported is a genuine defect in the function.

In particular, function’s documentation mentions *one-letter* sequences,
not *one-character* sequences:

	Return non-nil if a one-letter word is before point.

(Admittedly, the name of the function is misleading).

As such, I would suggest applying the fix to
‘fill-single-char-nobreak-p’ rather than introducing a new function.

(And perhaps adding an alias and deprecating the old name if misleading
name is too big of a problem).

As another point of context, ideally, ‘tildify-mode’ and
‘fill-single-char-nobreak-p’ would use the exact same logic since they
both work to address the same underlying typographic conventions.
