Subject: [ruby-core:27820] [Feature #2645] Have a method in StringScanner which returns the position in characters rather than in bytes

Issue #2645 has been updated by Kornelius Kalnbach.


+1...but what to name it?

* char_pos
* chpos
* index (like String#index)

by the way, the documentation for StringScanner#pos states:

  In the 'terminated' position (i.e. the string
  is exhausted), this value is the length of the string.

This is not true:

irb(main):002:0> s = StringScanner.new('������'); s.scan(/.*/); s.pos
=> 6
irb(main):003:0> s.string.length
=> 3
