Issue with spaces with sentence containing commas and periods. #235

I am seeing space issues after periods and commas in the "Welcome to Bitcoin Core" screen. See the screenshot attached.

Upon looking at the translation files, I don't see any immediate issues with the strings: https://github.com/bitcoin-core/gui/blob/54fc96ffa70ad3a53d32709101b7a2ce064d822e/src/qt/forms/intro.ui

I am running macOS Big Sur.

Seems to be a global issue, maybe?

Tested on Big Sur 11.2.2 (20D80) with a patch that allows select and copy the first paragraph:

Then the selected text pasted into the TextEdit:

Text is fine.

I think that the default macOS font issue is out of our scope.

Should we close the issue? @hebasto

Yes, I think.
