I think it's slated for 2.0 (or 1.9 first) Some possible workarounds:ruby 1.8.2 (2004-12-25) on powerpc-darwin8.0.0Welcome to Interactive Ruby us = '???ï??' ==>"???ï??" us.scan(/./) ==>["?", "?", "?", "ï", "?", "?"] us.unpack('U*') ==>[7782, 566, 529, 239, 331, 608]regexen will abide by the kcode, or you can unpack the utf-8 string asan array of integer code points.It shouldn't be too hard to wrap the regexp idea into a u_slicemethod. here's an untested lightwieght version: class String def u_slice(index, size = 1) self[/.{#{index}}(.{#{size}})/, 1] end def u_slice!(index, size = 1) str = self[/.{#{index}}(.{#{size}})/, 1] self[/.{#{index}}(.{#{size}})/, 1] = "" str end end
