@polkadot-js/api, one can encode a string
> u8aToHex(api.createType('String', "aabbcc").toU8a()) "0x18616162626363"
I know that SCALE encoding adds the length info at the beginning of the encoded result, so in total the output is 7 bytes instead of 6.
However, when I try decode the output back to a string, the leading byte is treated as part of the string instead of being stripped out.
> api.createType('String', "0x18616162626363").toString() "\x18aabbcc"
The expected result should be
aabbcc without the initial
So, how to get rid of the leading byte when decoding a SCALE-encoded string?
