Since MySQL utf8 charset doesn't implement unicode characters beyond BMP(U+10000 above), this means MySQL cannot support supplementary characters in metadata. 

For example, creating a table with supplementary character in its name will result in 0x3F in the table name.

We request MySQL to use utf8mb4 as the metadata charset.

How to repeat:
show variable like 'character%'
