commit-tree: encourage UTF-8 commit messages. Introduce is_utf() to check if a text looks like it is encoded in UTF-8, utf8_width() to count display width, and implements print_wrapped_text() using them. git-commit-tree warns if the commit message does not minimally conform to the UTF-8 encoding when i18n.commitencoding is either unset, or set to "utf-8".

commit-tree: cope with different ways "utf-8" can be spelled. People can spell config.commitencoding differently from what we internally have ("utf-8") to mean UTF-8. Try to accept them and treat them equally. Signed-off-by: Junio C Hamano <junkio@cox.net> 2006-12-31 04:20:43 +08:00			`int is_encoding_utf8(const char *name);`

Actually make print_wrapped_text() useful Now, it returns the current column, does not add a newline, and you can pass a negative indent, to indicate that the indent was already printed. With this, you can actually continue in the middle of a paragraph, not having to print everything into a buffer first.

Move encoding conversion routine out of mailinfo to utf8.c This moves the body of convert_to_utf8() routine used in mailinfo to the utf8.c i18n library. Signed-off-by: Junio C Hamano <junkio@cox.net> 2006-12-24 15:36:55 +08:00			`#ifndef NO_ICONV`
