[patch] plaintext output broken in branch and trunk

[Jürgen Spitzmüller]

Abdel, revision 21967 broke plaintext output. No plaintext file is generated, 
instead, an empty file named "UTF-8" is generated in the working directory.

The attached patch (against branch) fixes it, but still 
odocfstream::odocfstream(string const & encoding) obviously doesn't work as 
intended.
