Bug#18691: Converting number to UNICODE string returns invalid result.

Browse Source 
Conversion from int and real numbers to UCS2 didn't work fine: 
CONVERT(100, CHAR(50) UNICODE)
CONVERT(103.9, CHAR(50) UNICODE)

The problem appeared because numbers have binary charset, so,
simple charset recast binary->ucs2 was performed
instead of real conversion.

Fixed to make numbers pretend to be non-binary.
