I'm having some problems with XML/UTF8 and CGI variables in perl5.6.1
I have attached an example of the problem, an example string is Descripción -
although you will need to have XML::Simple installed.
The example takes an input string and then prints it twice - one with
concatenation another just displaying the inputted string. The mangling occurs
when you concatenate an XML string with a CGI string.
I'm not sure why this happens but here is a first attempt at a possible theory.
All XML parsing is done in UTF8, but perl has no idea of encodings for
incomding CGI streams and assumes them to be iso-88591 (latin1) - I read this
somewhere don't know if its correct. String operations upgrade none UTF8
strings to UTF8, so perl tries to convert the CGI string from iso-88591 to UTF8
thus mangling it as its already UTF8.
Can any point me in the right direction, explain where I'm going wrong and
maybe provide some usefull links - there seems to be very little information on
building internationalised web pages with UTF8 and perl5.6.1.
