I have a hash hard coded in the program (in ascii) and then I read some string from a XML file (in utf-8, string extract via libXML), the string and one of the key in hash are identical in content (same english alphabet), but the hash return nothing if I write in this way:

$value = $hard_code_hash{$utf8_string}

what happened?

I guess it may be the problem of the utf-8 string (query) and the non utf-8 string (key), but why it happen and any solution to this?

*the perl version is 5.8.5 (unix) and I can't upgrade it; store the perl file in utf-8 and call "use utf8" is not sound good as I do the programming on window, the utf-8 signature kill the perl interpreter
