The problem is a leading \n most likely.

---
L"\n<?xml version="1.0"...
---

Specification explicitly says that document prolog should be exactly at the
start:

http://www.w3.org/TR/xml/#NT-prolog

[22]       prolog       ::=       XMLDecl? Misc* (doctypedecl Misc*)?
[23]       XMLDecl       ::=       '<?xml' VersionInfo EncodingDecl? SDDecl? S?
'?>'

so no space characters is allowed before it.

I'll add a test for that, but before that please try that native one really
eats such input, cause it could be a problem somewhere else.
