[luatex] Fractions with custom glyph as rule

[Julius Ross]

Hi,
I see in the LuaTeX the \Uoverdelimiter and \Uunderdelimiter commands.  Is
there a sensible/peferred way to create a mathematics fraction that uses a
particular glyph for the horizontal rule between the numerator and
denominator?

(to be clear I am looking for a command that acts like \frac{a}{b} not like
the a/b that one can get with \Uskewed)

Thanks in advance!
