Bug #6161
closedDocument interpretation of backslashes in string transliterations
ruby -v:
ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-darwin11.3.0]
Backport:
Description
=begin
The transliteration string accepted by String#tr, #delete, #squeeze, and #count has its own backslash escape syntax (on top of that provided by string literals), but it isn't documented.
A backlash character escapes the subsequent character, unless it is the ending character of a range designator (e.g. (({X-}))) or the final character, in which case it is interpreted literally. This can be used to prevent a leading (({^})) from interpretation as the complement operator and (({-})) from interpretation as the range operator.
