read from a text file. * src/encoding.[Ch] (Encoding::latexChar): New, output a character to LaTeX (Encoding::validate): New, add needed preamble stuff for a character (Encodings::read): Read new unicodesymbols file (Encodings::isCombiningChar): New, is a character a combining char? * src/paragraph_pimpl.C (isEncoding): Delete, no longer needed (getEncoding): New, get the real encoding of a font (Paragraph::Pimpl::latexSurrogatePair): New, output a surrogate pair to LaTeX (Paragraph::Pimpl::simpleTeXBlanks): Use latexSurrogatePair if needed (Paragraph::Pimpl::simpleTeXSpecialChars): Ditto, and replace several hardcoded characters with a call of encoding.latexChar() (Paragraph::Pimpl::validate): replace several hardcoded characters with a call of encoding.validate() * src/support/debugstream.h (basic_debugstream::disable): New, disable the stream completely (basic_debugstream::enable): New, reenable the stream * src/lyx_main.[Ch]: Adjust to changes above * src/paragraph.C: Ditto * lib/unicodesymbols: New file with UCS4 -> LaTeX command mapping. It is far from complete yet, but contains most accents on latin characters. * lib/Makefile.am: add lib/unicodesymbols * development/scons/scons_manifest.py: ditto * development/tools/unicodesymbols.py: Helper script to update lib/unicodesymbols with new symbols git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@16920 a592a061-630c-0410-9148-cb99ea01b6c8
