[xsd-users] XML encoding

[Yianis Nikolaou]

thank you very much for your prompt reply!

I guess the standard Xerces library that I downloaded along with XSD does
not suport iso-8859-7 since I get an empty file when I call

project (ofs, p, map, "ISO8859-7");


The problem I am trying to solve has to do with Greek character (hence the
iso-8859-7).
When I run xsd with the default char size I get an exception
invalid_utf8_string from string.ixx when I use Greek characters in string
fields. When I use wchar_t it works fine, but the output is UNICODE and not
viewable by notepad etc.

Questions:
Q1: If Xerces recognized the iso8859-7 and I used wchars, then would I get
the correct output in iso8859-7 and not Unicode?
Q2: If I compile XSD with XSD_USE_LCP defined, would I be able to enter
Greek characters in standard char mode without getting the exception
invalid_utf8_string?

thank you in advance!

PS
Greek Characters, just in case you would like to test something (-:
