The fix for https://github.com/magento/magento2/issues/9619 is already in 2.1-develop branch thus will be released in one of the next 2.1.x versions.

I believe the same code is responsible for both text/visual swatch label validation, would be nice if you check if the issue is gone on 2.1-develop or 2.1.10-preview. Thus not marking as duplicate before confirmation.

I confirm that problem is resolved both 2.1-develop and 2.1.10-preview branch.

Thank you @orlangur for the investigation of this issue! 👍
Closing the issue. Fix will be available with 2.1.10 release

This doesn't appear to be fixed - We are still seeing the issue in v2.2.3. I also don't see any reference to the fix in the CHANGELOG. Can't someone point me to where this was fixed?
