Issue #7845 has been updated by matz (Yukihiro Matsumoto).


Five yeas have passed since the decision in [ruby-core:19379], and Unicode had almost taken over the world.
Maybe it's time to relax the limitation at least when we are using Unicode.

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-39157

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
 => "?????"
