Xml Parser and Utf-8 support

[ksgeograf]

When constructing an Xml document with Utf-8, it is common to insert the Utf-8 byte-order header: 0xEF, 0xBB, 0xBF before the leading encoding tag: <?xml version="1.0" encoding="Utf-8" ?>.

Inserting the tag ensures that the document will be displayed correctly when using non-xml capable editors (ea. text editors).

However, trying to submit an Xml document with the byte order tag gives an error in the Server:

An unclassified exception occurred.

An unclassified exception occurred. Exception occurred in method MgWebLayout.ParseWebLayoutDefinition at line 293 in file c:\build_bond_area\mapguide_open_source_v1.2\build_18.1\mgdev\web\src\webapp\WebLayout.cpp 

The problem seems to be that the MgXmlUtil::ParseString(...) does not check for the bytemarks, which makes sense, as it is supposed to read a string.

I am unsure where to fix this. Perhaps MgUtil::GetTextFromReader(...) should strip the byte marks before returning the string?

Perhaps MgUtil::GetTextFromReader(...) could be upgraded to handle multiple encodings, eg Utf-16 and ISO-8859-1?

Old ticket; closing. Kenneth, if you still think it is worth handling BOM, could you enter an enhancement request for it?
