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! -- Denis
