Encoding trouble

[Denis Bitouzé]

Hi,

several years ago, I already faced the following problem and,
unfortunately, it happened again yesterday, which made me lose quite
some time.

Let me explain myself: I had a LaTeX file encoded in latin1 that
I wanted to encode in UTF-8. I used an external tool, in this case
`utrac`, which confirmed the starting (latin1) and ending (UTF-8)
encoding. But, when I opened this file in Emacs with AUCTeX enabled, the
accented characters were wrong and it was only when I saw that the file
contained `usepackage[latin1]{inputenc}` that I understood where the
problem came from: changing it in `usepackage[utf8]{inputenc}` solved
it.

So, here is my request: would it be possible that, for the detection of
the real encoding of the file, AUCTeX relies not on the `inputenc`
package option, but rather on the Emacs heuristics and that, in case of
discrepancy between the two, it issues a warning?

Thanks!
