It would be good to get some info on how we can use this library for the utilities.

Thank you!

calling String_felt_to_string function with parameter 1

func felt_to_string{
        syscall_ptr : felt*, range_check_ptr, pedersen_ptr : HashBuiltin*
    }(elem : felt) -> (str_len : felt, str : felt*):
    let (str1_len, str1) = String_felt_to_string(elem)
    return  (str1_len,str1)
end  

got error

{"code": "StarknetErrorCode.SECURITY_ERROR", "message": "Invalid memory value at address 1:62: 12:3618502788666131213697322783095070105623107215331596699973092056135872020480."}

Hello team.
I have been working on a web UI that uses your library https://cairo-utils-web.vercel.app (repo).

During the use I can see that the library works as intended for a string like "ciao" -> 1667850607. But it returns a wrong result when the input is a simple number "1" -> 49, instead of "1" (both decimal and hex outputs are wrong).

I compared the output with something created by another person at https://util.turbofish.co/

Are you aware of this issue?
Thanks
