In certain character sets, the euro sign resides at character code $80.
In Unicode, it is at code $20ac, which is the only code an XML parser is
interested in since XML always uses Unicode.
However, an XML file may be *encoded* using any character set. The
<?xml?> processing directive at the top of the file should tell you what
encoding was used. Also consider whether the file starts with any
Unicode byte-order mark. If there is no byte-order mark, and the
processing directive has no encoding property, then you should assume
the file is encoded as UTF-8.
Your XML parser should expect a WideString as input. If it expects an
AnsiString, then it's probably not written correctly. (It *might* expect
an AnsiString encoded with UTF-8, but that's unlikely.) Read your XML
file and transcode it to be UTF-16, which is the encoding Delphi's
WideString type expects to hold. Your XML library might even have
functions for changing a string's character encoding.
