  Component:  Server     |     Version:  1.2.0

-------------------------+--------------------------------------------------
 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?
