# pipe output into cast for conversion. 👎🏼

I'd like to work on this issue :)

Also worth nothing that the following also works:

$ cast to-ascii $(cast call 0xdAC17F958D2ee523a2206206994597C13D831ec7 "symbol()" --rpc-url https://eth.llamarpc.com)

I will modify symbol() function to remove newline characters before returning the output.
