I will reply to each situation in a different message, for simplicity. :-) > -- Situation 1 -- > > Procedure: > - open a very old LyX 1.4 file saved in latin9 (or latin1) encoding > - make a minor modification and save, so that the file is converted to the new > lyx file format > > Current behaviour: > - the resulting file is silently converted to utf8 encoding, as described by > the "file" command or a text editor > - the file is still described as latin9, via the line "\inputencoding iso8859- > 15" in the lyx file > > Consequence: > - everything works fine, except that the tex export is latin9 Notice that there are two different encodings here: * the first is related with the file encoding; * the second is the encoding of the exported (latex) file.

This is supposed to happen, if it does not work then this is bug that needs to be fixed. The transition to utf-8 was done in 1.6 (IIRC). I will look into this issue.
