|Yes, it's a bug.  Thank you.

Although I thought it was a feature bug against consistency, it found
out to be a spec to make regular expression work well under mixed
encoding circumstances, after struggling for a whole day.  So regular
expressions that contain only 7bit characters reports US-ASCII for
their encoding, at least during the 1.9 era.
