Environment

jruby-9.1.7.0 running on Linux 4.13.13-100.fc25.x86_64 #1 SMP Wed Nov 15 17:33:19 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Expected Behavior

\X should match the letter à in the form of a graphene encoded as U+0061 U+0300. The MRI shows the expected behavior:

$ irb
2.3.1 :001 > x = "h\u0061\u0300llo"
 => "hàllo" 
2.3.1 :002 > x =~ /h\Xllo/
 => 0

Actual Behavior

\X does not match the graphene using JRuby.

$ irb
jruby-9.1.7.0 :001 > x = "h\u0061\u0300llo"
 => "hàllo"
jruby-9.1.7.0 :002 > x =~ /h\Xllo/
 => nil

Corresponding issue for the jruby/joni package.
