[ruby-core:67193]

Description

The following simple script illustrates the issue:

ESCAPE_PLAIN = /\A[\x5B]*\z/m.freeze

0x5B.chr(::Encoding::UTF_8) =~ ESCAPE_PLAIN
0x5B.chr =~ ESCAPE_PLAIN

\x5B is ']', run all lines above and get in `=~': empty char-class: /\A[\x5B]*\z/m (RegexpError)

Comment out either the first or second usage and the error goes away.
