I was reading the tr's man page. In same cases it shows two syntax versions:
/usr/xpg4/bin/tr
c-c
/usr/bin/tr
[c-c] Represents the range of collating elements
For \n there is only one explanation version but in practice it works or not on
some trs. I do not know what are the real differences between the standards.
\octal has also single explanation but additionally it also works in the same
way between the versions.
