No, changing encoding occur refreshing. So It can't use char2nr gracefully.
The changing &encoding option affect to substitute(), strXXX or many another
functions. The new feature I want is, getting character from utf-8 codepoint, Just
it.
Well, if you set your 'encoding' to utf-8 once and for all in your vimrc
(before any file is loaded), char2nr() will give you the Unicode
codepoint number of the first character in its String argument.
Similarly, nr2char() will give you (as a single character of one or more
bytes) the Unicode codepoint corresponding to its integer argument.
I don't understand your sentence "it can't use char2nr gracefully". If
'encoding' is set to utf-8, you'll need some fancy footwork to get the
character's value from the 'fileencoding' point-of-view if different,
but it's possible via iconv().
Best regards,
Tony.
