DatePart function returns a asterisk

I found a DATEPART Function returning an asterisk this morning for a backup job dynamically building the backup path. I just thought I'd share it since I doubt they will fix it.

--Run this in SSMS

select CAST(DATEPART(mm, getdate()) as CHAR(1))

--This returns a '*'   , but it should throw an error for overflow.

--Below is the fix in the string concatenation so it doesn't return a '*'

select CAST(DATEPART(mm, getdate()) as CHAR(2))
