Does EOS support signing a string?

Question

Ethereum has web3.eth.personal.sign that supports signing any string.

Obviously EOS supports signing transactions, but I don't see any support for signing a string.

Have I missed this or does EOS not support this functionality?

There are many Wallets out there that are supporting Arbitrary Signatures (with some limitations). From what I know there's no Metamask-Style Wallet (Browser-Extension) and only Desktop-Wallets which support them.

Take a look here: Scatter-Arbitrary-Signtaure

here: Scatter-Arbitrary-Signature-Limitations

and here: Lynx-Arbitrary-Signature

Based on your question I assume that you are looking for a possibility in javascript?

Eosjs doesn't support signing a string but eosjs-ecc does.
