Bug #172: Regular expressions should inherit encoding of context even if they only contain 7-bit chars

• Status: Closed

=begin
The following program fails:

encoding: utf-8

"∂y/∂x = 2x" =~ /\p{Greek}/

with "t.rb:2: invalid character property name {Greek}: /\p{Greek}/"

The reason is that the regexp has US-ASCII encoding, and in that encoding the property 'Greek' is not defined.

However, in this case, that's very unexpected behavior. I'd suggest that if a regular expression is US-ASCII, but is being compared to a string that is not US-ASCII, the regular expression should temporarily take on the same encoding as the string.
