uscalar

Returns the Unicode scalar value for the first Unicode character in "string_expression". If the first character is not the high-order half of a surrogate pair, then the value is in the range 0..0xFFFF. If the first character is the high-order half of a surrogate pair, a second value must be a low-order half, and the return value is in the range 0x10000..0x10FFFF. If this function is called on a Unicode character expression containing an unmatched surrogate half, the operation is aborted.
