Regular expression to match non-ASCII characters?
...
This should do it:
[^\x00-\x7F]+
It matches any character which is not contained in the ASCII character set (0-127, i.e. 0x0 to 0x7F).
You can do the same thing with Unicode:
[^\u0000-\u007F]+
For unicode you can look at this 2 resources:
...
sed error: “invalid reference \1 on `s' command's RHS”
...capture for that to work? i.e. for variant 2:
-r -e "s/WARNING: (\([a-zA-Z0-9./\\ :-]\+\))/${warn}WARNING: \1${c_end}/g" \
(Note: untested)
Without the -r argument back-references (like \1) won't work.
