implementation of new unicode character "latin capital sharp s " = upper-case eszett = 0x1e9e

That is generally not needed.  The symbol U1e9e works.

I would expect so.  I know that it was added to DejaVu Serif and
DejaVu Sans; I expect DejaVu Sans Mono will also get it by the
next release.

The easiest solution, for apps which support fallback fonts, would be to
create a family of fonts with that one glyph, using the ß glyph from your
favorite font family.

If you are using server-side bdf fonts, just edit them locally and add
a glyph for U+1E9E.

NB that, per the UCS and Unicode, uc("ß") != "ẞ"; it is still the case
that uc("ß") == "SS".

As such, support for U+1E9E may arrive a bit slower than for some other
additions to the UCS.
