I used the translate commands as follows:


1) tr -c ' a-zA-Z0-9,\n' ' ' < inputfile > outputfile ==> No result

2) tr -c '[:print:][:cntrl:]' ' ' < inputfile > outputfile ==>

The second command replaced one of the invalid character with space but retained all others. When I again ran the command on the resulted file, the complete files.(input as well as output.)

Please tell me some other combinations.

Among the following characters, ~æ£ÇÄ, Ç was replaced.

Thanks in advance.
