fixing (invalid coding)

[rikona]

I have been doing lots of file copies/restores in a new box. Turns out
many files have 'odd' characters in them that seem to be causing
problems in 12.04. Some software [like grsync] does not work properly
with these files. CLI with sudo seems to do well though - it seems to
be GUI pgms that have trouble. The offending files have '(invalid
coding)' tacked on the end of the name [in the GUI].

The chrs seem to be in foreign file names, especially German.

I have hundreds [+] of these in a wide variety of locations. It's not
possible to look through all the files, in thousands of dirs, to find
them. Is there a way to list ALL the files that have this problem
and/or fix it in the file name by, say, substituting a like-sounding
OK chr in the name?

Thanks...
