Given a directory of filenames consisting of double-byte/full-width numbers and spaces (along with some half-width numbers and underscores), how can I convert all of the numbers and spaces to single-byte characters?
For example, this filename consists of a double-byte number, followed by a double-byte space, followed by some single-byte characters:
2 2_3.ext
and I'd like to change it to all single-byte like so:
2 2_3.ext
I've tried convmv to convert from utf8 to ascii, but the following message appears for all files:
"ascii doesn't cover all needed characters for: filename"
