In case set2 is longer than set1, the remaining characters from set2 will be ignored. -.B -Character escape sequences, be them characters or octal numbers, are done preceding the token with a "\\". You may specify three digits or less for it, -digits will stop being read when a non-octal character or when three characters are read. -.B -Use "A-B" for ordered sets fom A to B. -.B -.SH NOTES -.B tr -is Unicode-aware, but only if you don't specify characters in octal (for example \\012), because else it is not predictable.
