How do I escape a Unicode string with Ruby?

Question

I need to encode/convert a Unicode string to its escaped form, with backslashes. Anybody know how?

Answer 1

try this gem. It converts Unicode or non-ASCII punctuation and symbols to nearest ASCII punctuation and symbols

https://github.com/qwuen/punctuate

example usage: "100٪".punctuate => "100%"

the gem uses the reference in https://lexsrv3.nlm.nih.gov/LexSysGroup/Projects/lvg/current/docs/designDoc/UDF/unicode/DefaultTables/symbolTable.html for the conversion.
