From Wang Rui, "A Chinese engineer (named Beilei Geng) reports a possible bug in the

osg2cpp application to me today. The conversion result may become
incorrect if there are quotation marks ( " ) in the shader file, which
will mostly appear in comment lines.

Replace all " into \" before writing to cpp files will solve the
problem, as the attached file shows."
