[PATCH] Disable unicode_strings when working with regular expressions Mojo::Base 0.50 enables unicode_strings feature in the scope where it used from. As a result, deserializing a regular expression injects qr//u flag to regexp object although the was no such flags in the deserialized BSON. The same issue repeats in t/bson.t when shuffling with the regular expressions.
The consequence is that a t/bson.t test fails.
This patch fixes it with disabling unicode_strings feature where needed.
