Issues
It should work on all Ruby 1.9.1 implementations or higher
independently of operating system. If not, please report
it on Issues · lang/unicode_utils · GitHub
All tests pass with jruby-1.7.0.RC1. Not all tests pass with
MRI 1.9.3p194 due to unexptected behaviour of String#<< with
UTF-16 strings. As long as you use only UTF-8, there’s no problem.
(Bug #7090: UTF-16LE String#<< append 0x0 for certain codepoints - Ruby master - Ruby Issue Tracking System).
