[Libreoffice] [PATCH] Replace (Byte)String with O(U)String

[Chr. Rossmanith]

Hi,

this is a modified version of the previous patch which takes into 
account improvements suggested by Caolan and Stephan. Please don't push 
yet because the caller of RecodeString() has to be touched as well. Does 
that modification have to be contained in the same patch or do I just 
have to make sure that the two commits are pushed together? A second 
review is very welcome.
