If this is what you want use len(split(str[: match_start-1], '\zs')). Use strchars(str[: match_start-1]) if you want them counted separately. Use strdisplaywidth() if you need count for the jump-to-virtcol (pipe) motion. > > Yes thanks, I've already found that I can use strchars() for that. By "symbol" I meant "char", sorry for wrong term.
Meaning of "char" is unclear as well. If strchars() is fine it should be "unicode codepoint" (because "composing characters are counted separately"). Problem is that I do not know well-established terminology on this matter: display cell, byte and unicode codepoint each have single clear meaning, but symbol and character may mean anything, depending on the speaker. > > -- > -- > You received this message from the "vim_dev" maillist. > Do not top-post!
