What's your locale, esp. the LC_COLLATE variable?


Try that command prefixed with LC_ALL=C.

No. It will remove characters that are not in the "ASCII range" from 0x00 up to 0x7F. ASCII control chars (non- printable, incl. white space) will NOT be removed. It will remove characters above ASCII, starting with 0x80 (= 128), including "extended ASCII" or any other character set / encoding like UTF-8, on which your locale setting may depend.


You may want to consider starting over, making up your mind which chars you need, and which you don't, and rephrase your specification. Do you have examples of "target" chars ?
