Bug #7845: Strip doesn't handle unicode space characters in ruby 1.9.2 & 1.9.3 (does in 1.9.1)
https://bugs.ruby-lang.org/issues/7845#change-39127

Author: timothyg56 (Timothy Garnett)
Status: Rejected
Priority: Normal
Assignee: naruse (Yui NARUSE)
Category: M17N
Target version: current: 2.1.0
ruby -v: ruby 1.9.3p286 (2012-10-12 revision 37165) [x86_64-linux]
Backport: 


Strip and associated methods in ruby 1.9.2 and 1.9.3 do not remove leading/trailing unicode space characters (such as non-breaking space \u00A0 and ideographic space \u3000) unlike ruby 1.9.1.  I'd expect the 1.9.1 behavior.  Looking at the underlying native lstrip! and rstrip! methods it looks like this is because 1.9.1 uses rb_enc_isspace() whereas 1.9.2+ uses rb_isspace().

1.9.1p378 :001 > "\u3000\u00a0".strip
 => "" 

1.9.2p320 :001 > "\u3000\u00a0".strip
 => "?????"

1.9.3p286 :001 > "\u3000\u00a0".strip
 => "?????"
