Yes, That's what I meant. 

I was testing the demo_xml_load.cpp and  demo_xml_save.cpp available in
the boost.serialization example.
By simply opening demo_save.xml produced by demo_xml_save.exe with XML
copy editor(http://xml-copy-editor.sourceforge.net/) and saving it back,
demo_xml_load.exe would crash. I compared the two files with Winmerge.
It said it's identical.

by studying the hex view, I later found it's because the 3-byte UTF-8
BOM was inserted to the beginning of file. It would not change the data,
and in many cases was ignored by the text editors.

I thinking that Boost.serialization should also handle this for all text
files including XML.
