Set from decimal (0 to 255)

A byte is 8 bits, so it can hold 256 values, 0 to 255. Signed shows the same bits read as two's complement, where the leftmost bit counts as -128. Character shows the ASCII character for values 0 to 127. Values 128 to 255 are not ASCII (shown as none); in UTF-8 they only appear as parts of multi-byte characters.

ASCII has 128 codes (0 to 127). Codes 0 to 31 and 127 are control codes, shown by their short names. In UTF-8, these characters use one byte each, the same as in ASCII. ASCII on Wikipedia
