Always use UTF-8 mode with certain files

Always use UTF-8 mode with certain files

[Juha Nieminen]

Hello.

I would like for emacs to always use UTF-8 mode when opening certain
files (similarly as to what happens if I do a C-x C-m r utf-8, but
just when normally opening a file.) For example I would like this to
be the case when opening files with extensions .m, .mm and .h.

I don't know what to write in the .emacs file for this to happen. (And
obviously it shouldn't interfere with any other hooks that are
triggered when opening such files...)

This isn't a direct answer to the question, but I would point you to
tip #1 in https://github.com/sdegutis/using-emacs#tips-about-pragmaticism

You can open all files, except they have local variables set or similar settings to open in a different encoding, by setting in your environment LANG and LC_CTYPE to some UTF-8 value. In your init file you can set additionally:

	(prefer-coding-system 'utf-8)

For /some/ instead of all file types you could use statements à la:

	(add-to-list 'file-coding-system-alist '("\\.m\\'" . utf-8))

We have to expect it, otherwise we would be surprised.
