Looking at character frequencies in web documents, the frequency of U+0673
cannot be separated from noise. Haven't yet looked at URLs.

> > The UTC has recently approved a proposal to encode an ARABIC WAVY
> > HAMZA BELOW for a future version of the Unicode Standard. That
> > character is used productively in Kashmiri and other languages, and is
> > applied to letters other than ALEF. The intent is to deprecate the

> > favor of the sequence of an ALEF plus the new ARABIC WAVY HAMZA BELOW.
> > (Because of normalization stability constraints, a canonical
> > equivalence relation cannot be established.)

> > The UTC is seeking feedback on whether U+0673 should be deprecated
> > when ARABIC WAVY HAMZA BELOW is encoded. Pertinent information would
> > include data on how widespread usage of this character is. Note that
> > deprecation of a character does not mean removal of that character
> > from the standard; it merely constitutes a strong recommendation not
