[ruby-core:54825] [CommonRuby - Feature #7845] Strip doesn't handle unicode space characters in ruby 1.9.2 & 1.9.3 (does in 1.9.1)

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


Everything that can be resolved without locale/language information (for most of the cases).
Case conversion may have problems with some characters, e.g. german eszett or turkish i, but can be converted mostly.
Of course it would take time to implement everything, but the basic principle (and goal) will be.

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
 => "　 "
