ZyX, Thanks. I don't want to use option (1) for performance reasons. Option (2) almost worked; however, it fails to replace some characters.
I wonder if I'm doing the "mappings" table correctly. Does this look right? map(range(128,255), 'iconv(nr2char(v:val),&enc,"latin1")') The character sequences that are not replaced start with these characters. Should these be escaped? dec: 221, <M-]> dec: 193, <M-A> dec: 215, <M-Z> ... If I switched from "utf-8" to "latin1", then everything works perfect. It has something to do with the encoding mode. Thanks again!
