There was a time, quite very early on in electronic computing, when the numerals were represented in adjacent positions in the character set, in the order '1', '2', '3', '4', '5', '6', 7', '8', '9', '0' . That time is long long gone, and for well over 60 years all character sets have represented the numerals as adjacent positions in the character set, in the order '0', '1', '2', '3', '4', '5', '6', '7', '8', '9' .
There have been character sets such as IBM's EBCDIC that put those characters in different starting point than is now standard.
No matter where the block of numerals is in the character set, if you can be sure you are not working with 1940's character sets, then you can figure out the decimal value of the '0' or '1' characters by figuring out the offset from the '0' character, by subtracting the internal representation of the '0' character. '0'-'0' is 0, which is what you would want in decimal, and '1'-'0' is 1 because '1' is known to be the character immediately adjacent to the '0' character.
