But section 2 in the specification is a grammar. A single null byte is not sufficient for this code, because many Unicode characters contain null bytes as either the high or the low byte. I've checked it and decided to write an ABICoder on my own because I would have to change anyways a lot of things. The ethers.js coder was used because it is robust and well tested and was the only implementation of ABIv2. Everything returns with 0's even though I know that is incorrect. How can we convert 66 characters length of string to bytes32 and pass to execute function to achieve same result i.e, recovered accounts are same to actual accounts where we sign.

Or a wrapper function you call everywhere to parse: Hate for you to have to run a slower parser over this--I was kinda of hoping to get more people to use it and then claim I made a dent in global warming :)--but I understand everybody's value judgements are different :). If I can't solve these issues until the end of the day I will downgrade to an older version of ethers.js. Solidity and the block chains are strongly typed, so there is not way to coerce these two types into each other, even manually. This is not behaviour that will be supported in ethers.js, but once I've figured out what it is doing, I can create a sample function to help people who are already relying on the web3 bug. Didn't do ethers.utils.concat([bytes, Zeros]).slice(0, 32). What I mean is (for example) that you don't have to do. Let us see what happens if you load a document with a final nul in JavaScript: So if you pad the end of your JSON strings with nulls, they won't parse in JavaScript and Python.
