#1314214-82: UTF-8: support 4 bytes characters in MySQL:
It's probably worth tidying up our schema (for example: machine name-type keys should probably use a ascii character set so as to reduce the size of the index)
The default regex on machine names limits the characters in machine names using the following regex [^a-z0-9_]+ so only ASCII characters are used.
The improvement @sun proposes is for the schema of the table column that stores machine names :)
