I am trying to write a plsql routine that will delete a range of characters based on their octal or hexadecimal values.  Something like the 'tr' shell command will do:

cat file| tr -d ['\177'-'\377']

Can't seem to figure this one out.

Pointers would be appreciated.

Would the string functions to_hex(), translate(), replace() and friends work for you?
