I have put a few ideas in a document 'alternatives.markdown' at the same 
location.

The other possibility which may make sense is to transcode 
automatically. For example, in

  s3 = s1 + s2

then s2 is transcoded to s1's encoding, and the result s3 always has 
s1's encoding.

That could actually be useful in helping to combine strings from 
different sources. All the compatibility rules would vanish, and rather 
than raising exceptions, ruby would just "do the right thing". 
Transcoding to BINARY/ASCII-8BIT would be a null operation, so building 
a binary string would be safe too.

This isn't a total U-turn, but it would be quite a major shift and I 
suspect too big for 1.9.x.
