number symbols from strings in scheme

yo'
stop talking about the jews for a moment and help me, thanks.

I'm toying with scheme evaluator and I'd like to know why the conversion from string to symbol, lets say (string->symbol "1"),
returns things as |1| and not '1 that eval or the language itself would recognize as a number.

the number 1 isn't the same thing as a symbol whose name is "1"

further example: 1a is a syntax error but you can still have a symbol named "1a"
