Re: Win32::OLE - ? encoding of returned strings

[Mike Trotman]

Thanks - that's very useful. And I had missed the Unicode mode in the Win32::OLE documentation. To clarify: Part of my problem is that the MSXML XSLT transformations do NOT output the character encoding in the XML declaration. So - $xmldoc->transformNode($xsltsheet) may output Windows-1252 encoded data - but does not contain encoding='Windows-1252' in the <!? xml version='1.0'?> and so other parts of the process expect it to contain UTF-8. If I turn on the Win32::OLE UTF8 code page for a Win32::OLE call to MSXML that returns a UTF-16 string (or Windows-1252) - is the automatic conversion to UTF8 likely to be correct - or incorrect? IE - does the automatic conversion correctly detect the CP of the OLE output?

I suspect that something in the way I am passing data around (or in the ADO implementation of 'savetoxml') is not dealing correctly with XML document encoding declarations. The data is originally in an MS Access database - but has been entered using copy and paste from MS Word documents from around the world - so contains many weird and wonderful bytes. To help in my debugging process can anyone tell me how WIN32::OLE deals with 'strings' returned from method calls? i.e. - are they pure byte data as output by the method (and maybe in UTF-16)? - or are they converted to Perl's internal format (using any current Perl encoding settings)? - or does something else happen? The problems I am having are primarily when outputting XML documents (or HTML) to send to the browser. e.g.my $OUTPUT=""; $OUTPUT=$xmldoc->transformNode($xsltsheet); print $OUTPUT; All string data is converted to the current system codepage by Win32::OLE before being passed back to Perl _unless_ you switch Win32::OLE to Unicode mode first: Win32::OLE->Option(CP => Win32::OLE::CP_UTF8()); After this call all strings are converted to UTF8 and marked as such in the Perl internal flags.
