bug#2666: 23.0.91; TeX calendar and UTF-8 encoding

I have localised calendar to show month and day names in German. This month is März. When I create a (La)TeX calendar, it's in UTF-8 (because of my shell environment), the ä is 0xC3 0xA4 or ä in ISO 8859-1 or À in ISO 8859-15. The latter is my preferred LaTeX input encoding since it allows to use our currency sign, the €. This now makes it necessary to use the textcomp package in LaTeX.

Is it possible to make the output produced or its encoding more flexible, adapt itself to the default encoding of GNU Emacs? If not, could the documentation be updated to state which encoding is used and that the user should use cal-tex-preamble-extra to adapt for that?

I have some difficulties with the documentation of cal-tex-preamble- extra. Its doc-string contains

   For example, to include extra packages:

but when I use \\ and \n in the customisation interface these appear unchanged in the calendar.tex buffer. (Actually LaTeX does not complain when a few commands are concatenated to build a long line.) I haven't yet saved my customisation – if this explains the difference between theory and practise.

I'd also recommend to use the report class instead of article in the LaTeX output generated: no useless AUX file is created then. Other differences won't show up.

Another improvement would be to update some old LaTeX code, for example the


This would only work for ancient DVI output. Modern XeTeX and pdfTeX do not understand this. A completely orthogonal solution is:


Between ``[´´ and ``]´´ is also the correct place to define the margin:


It should be OK to just use:


It's not necessary to set \textwidth and \textheight. There is probably no-one using a TeX distribution elder then 15 years, i.e., it will be teTeX or TeX Live based. In these distributions a TeX configuration file sets the default paper size. To switch from landscape to portrait just remove the ``landscape,´´ option from the line loading the geometry package or set clearly:


This package is in all TeX distributions. Since some years (<10) this is also true for the Latin Modern fonts (texdoc lm-info), which are planned as a modernised update and substitute of all CM fonts in a modern font format (OTF), which can be loaded via


(actually PostScript fonts are used here). It could also be thought of making the LaTeX output XeTeX compatible (loading ifpdf and ifxetex packages, loading the fontspec package for XeTeX and setting a system font, for example Times, or leaving the default Latin Modern).
