Issue #13110 has been updated by shyouhei (Shyouhei Urabe).


We looked at this issue at today's developer meeting.

I remember no one there had strong pro- or contra against byteoffset and byteindex. But what about bytesplice? Seems a programmer can pass arbitrary byte index to it.  That can be troublesome because the passed index might be a middle of some code point.

Feature #13110: Byte-based operations for String

How about to add byte-based operations for String?

```ruby
s = "あああいいいあああ"
p s.byteindex(/ああ/, 4) #=> 18
x, y = Regexp.last_match.byteoffset(0) #=> [18, 24]
s.bytesplice(x...y, "おおお")
p s #=> "あああいいいおおおあ"
```
