module UTF8Encoding
# Allows any supported object to have any high-ascii string
# content to be force-encoded from UTF-8 to BINARY (/ASCII-8BIT).
# This ensures that any serialisation to YAML, using Psych,
# can be stored in other encodings. (Psych by default emits
# UTF-8 YAML, which might not survive being stored in a Windows-1252
# database, for example.)
