[texinfo-pretest] Problematic glyphs in HTML output

[Torsten Bronger]

Hallöchen!

In HTML output, some characters (e.g. Hungarian umlaut, Polish
l-slash, dotless i) are not printed nicely, but rendered as ASCII.
Unfortunately, this also affects XML output, so I noticed.

The reason stated in the source is that these characters "don't have
HTML support".  I think this statement is rather outdated.  Very
most browsers can digest &#....; for giving an arbitrary Unicode.
It's part of the standard for many years.

XML can do anyway, but before a lot of new "if"s pollute the source,
I wonder whether you agree that this should be fixed for HTML, too.
I even think that one should fix the "Glyphs for Examples" like
"==>" or "-!-", since there are Unicodes for them, too.

What do you think?

Tschö,
Torsten.
