Get the position for String {expr}. Same as getpos() but the column number in the returned List is a character index instead of a byte index. If getpos() returns a very large column number, equal to v:maxcol, then getcharpos() will return the character index of the last character.

Example: With the cursor on '세' in line 5 with text "여보세요":

getcharpos('.')         returns [0, 5, 3, 0]
getpos('.')             returns [0, 5, 7, 0]

Can also be used as a method:

GetMark()->getcharpos()
