I tried to see if converting to binary would expose a character type, but the beginning of binary out looks same in both cases.

DECLARE @REALNAME varchar(255)

SET @REALNAME = 'Ricki Ricardo'---leading space is a tab

select LEN(@realname)

select len(RTRIM(ltrim(@realname)))

select charindex(char(9),@realname, 0)

select convert(binary(15), @realname)--yields 0x095269636B69205269636172646F00

SET @REALNAME = ' Ricki Ricardo'

select LEN(@realname)

select len(RTRIM(ltrim(@realname)))

select charindex(char(9),@realname, 0)

select convert(binary(15), @realname)--yields 0x205269636B69205269636172646F00
