# It ensures that two identical byte secuences are matched regardless
# they have different encoding.
# For example in Ruby the following returns false:
# "iñaki".force_encoding(::Encoding::BINARY) == "iñaki"
def self.string_compare string1, string2
string1.to_s.force_encoding(::Encoding::BINARY) == string2.to_s.force_encoding(::Encoding::BINARY)

# This avoid "invalid byte sequence in UTF-8" when the directly doing:
# string =~ /EXPRESSION/
# and string has invalid UTF-8 bytes secuence.
# Also avoids "incompatible encoding regexp match (UTF-8 regexp with ASCII-8BIT string)"
# NOTE: expression argument must be a String or a Regexp.
