using texlive:latex/pdflatex/xelatex and shebang (jobname)

Question

I'm wondering, why my minimal example (in file shebang.tex)

%& -job-name=test
\listfiles
\documentclass{article}
\begin{document}
Hidiho
\end{document}

will always (no matter if using latex, pdflatex oder xelatex) compile to shebang.dvi/pdf and not to test.dvi/pdf. Are shebang-lines deactivated?

Edit: I just found out, that it is something with encoding: Using MikTex in Windows on the file encoded in ISO-8859-15 it is working - but not with encoding UTF-8 - which I like to use.
Under Debian Linux with texlive, no matter which encoding it is not working.
Maybe one needs another symbol after the percent-symbol?
The questions seems to be somehow related to %& magic line has no effect: But there is also a difference: Running the command xelatex -parse-first-line shebang will also produce shebang.pdf. In the log file, there occur those lines

 %&-line parsing enabled.
**shebang
(./shebang.tex
\openout1 = `shebang.aux'.

showing the flag being recognized - but the job-name not working.

Answer 1

The MikTeX documentation specifies the %& option can be used to add additional command line parameters. It uses miktex-pdftex though, instead of just pdftex. The pdflatex man page suggests the %& option can only be used for format files and -translate-file options.

-parse-first-line

If the first line of the main input file begins with %& parse it to look for a dump name or a -translate-file option.

You could of course write your own wrapper script that parses the first line and then calls pdflatex or xelatex or your engine of choice with the suggested parameters. I am guessing this is basically what miktex-pdftex does.
