Just googled "Binary translator" and inputed the names of the characters into it (personally I know only how to represent NUMBERS in binary, and nothing else).
Well, they still are numbers, characters have assigned value in the ASCII table. Specifically 65-90 for upper-case alphabet and 97-122 for lower-case alphabet. Those numbers should fit each row.
Those numbers should fit each row.
ASCII has A=65, B=66, ..., Z=90 a=97, b=98, ..., z=122, <space>=32.
