publish.m: Support some non-ASCII characters in comments for pdf output. * scripts/miscellaneous/publish.m: Clarify documentation. Publishing Markup is only interpreted in section comments. Remove sentence that suggests that commands in the output format might be interpreted in that format. * scripts/miscellaneous/private/__publish_latex_output__.m: Add substitution rules for some multi-byte UTF-8 characters (mostly Latin-based) to LaTeX publish template. This fixes a bug where using these characters in comments would cause `pdflatex` to fail. See: https://github.com/gnu-octave/octave/pull/5
