How to sign a message?!

[Cantsay]

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
Thank you Shorena for the great tutorial, I'm signing this message to show that I didn't only just look at the post but also learnt something from it.
-----BEGIN BITCOIN SIGNATURE-----
Version: Bitcoin-qt (1.0)
Address: 1Ex3cMqXFAnjPi6T6SEySF37Pvu3172bkh

-----END BITCOIN SIGNATURE-----

Edit:

It looks like he accidentally added a single whitespace at the end of the message (after the dot

Thanks for spotting the error, I have corrected and verified it with mycelium wallet. But I will still appreciate if you can also verify the message for me.

It seems that something is wrong with your signed message ^{[e.g. it could be an extra space or something like that]}... I had no luck in verifying it with Bitcoin Core, Trezor Suite, Electrum, and Brainwallet!
^{- Sign another message and check if you can verify it on "Brainwallet".}
You might want to sign a message on the following thread as well: Stake your Bitcoin address here

Update:

It looks like he accidentally added a single whitespace at the end of the message (after the dot) but omitted it in that reply.
But it can't be verified by any tool aside from Brainwallet's Verify Message - Bitcoin-QT tab and manually adding the "space".

Great catch

His signed message in this board can be verified though: /index.php?topic=5300698.msg60497828#msg60497828
