Bug #647: Source encoding not applied to 7-bit regular expressions

• Status: Rejected

=begin

encoding: utf-8

"cat".encoding # => #Encoding:UTF-8
"δδδ".encoding # => #Encoding:UTF-8
/cat/.encoding # => #Encoding:US-ASCII # <<<<
:δδδ.encoding # => #Encoding:UTF-8

I was expecting the regular expression to be encoded the same way a
string is.

Matz: Yes, it's a bug. Thank you.

memo:
If source encoding applied to 7-bit regular expressions,
we need Regexp#ascii_only? and special treatment in Encoding.compatible?.
