Make the output of \inputencoding commands (and the change of output encodings) more fine grained: From paragraph level to individual character level. The inputenc package supports that since at least 2000. * src/insets/insetbase.h (latex): Document the differences between output to a string stream and a file stream * src/buffer.h (writeLaTeXSource): ditto * src/output_latex.h (latexParagraphs): ditto (switchEncoding): new function to change the encoding of a stream (and output \inputencoding commands) * src/paragraph_pimpl.C (Paragraph::Pimpl::simpleTeXSpecialC): Adjust to latexWriteEndChanges changes * src/support/docstream.[Ch] (setEncoding, operator<<): New stream modifier that changes the encoding of file streams * src/lyxfont.[Ch] (LyXFont::latexWriteStartChanges): Change stream encoding if needed (LyXFont::latexWriteEndChanges): Change stream encoding if needed * src/lyxfont.h (public:): * src/paragraph.C (Paragraph::simpleTeXOnePar): Adjust to latexWriteStartChanges and latexWriteEndChanges changes (bool Paragraph::simpleTeXOnePar): (bool Paragraph::simpleTeXOnePar): (bool Paragraph::simpleTeXOnePar): (bool Paragraph::simpleTeXOnePar): (bool Paragraph::simpleTeXOnePar): * src/output_latex.C (TeXOnePar): Remove the ugly hack to for wencoding changes and use switchEncoding instead. A nice side effect is that the old hack would not work if the main language encoding is latin1 and a character would be mapped to a cedilla in the "fake ucs4" encoding, because iconv refuses to convert such a character to latin1, although it exists in latin1 (it wants to attach it to a base character). git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@16633 a592a061-630c-0410-9148-cb99ea01b6c8
