Unicode: Do the conversion of error messages to docstring where they are read

in, because we don't know the encoding of external files.

	* src/LaTeX.C
	(LaTeX::scanLogFile): Convert error strings to docstring and add
	a comment that this could be wrong

	* src/Chktex.C
	(Chktex::scanLogFile): Ditto

	* src/LaTeX.h
	(TeXErrors::error_desc): Convert to docstring
	(TeXErrors::error_text): Convert to docstring

	* src/buffer_funcs.C
	(bufferErrors): no from_utf8 needed anymore
