Those which match the regexp ".*utf\\(-?8\\)\\>".

It sets the language environment to "utf-8", and sets the default and 
preferred coding systems to utf-8.  It also sets the default input 
method.

The values of LANG/LC_ALL are used to set the language environment and 
the locale-coding-system (the latter is used on X for decoding X keysyms, 
which is important when the keyboard sends non-ASCII keysyms, like with 
dead keys).  That is what I meant by ``turning on the UTF-8 locale''; 
sorry for the vague wording.
