#11 special characters show up as garbage

[Reinhold Kainhofer]

Special Characters like the \DoubleStruckR,
\AliasDelimiter, etc. are not converted right
(actually, garbage is written out, because the
Unicode character is split up into two characters,
one having a character code of the lower, the other
the code of the higher part of the original unicode
character code). This is not CSSSave's fault, but
HTMLSave's.
