Force encoding for binary string literal in the tests.
Force encoding for binary string literal in the tests.

Ruby < 2.0 interprets string literals as ASCII-8BIT by default, but
>= 2.0 assumes all string literals (and source files) are in UTF-8.
Calling force_encoding ensures this string is interpreted as binary.
