Good news, we now have a fix available for this in build 11.0.75. This new version is available on the alpha channel.
The Alpha channel contains frequent updates and provides access to the very latest versions. It is the recommended channel if you have an urgent need for a fix that is not yet available on the Stable channel and do not mind frequent updates.
To get on the Alpha channel:
Windows: Go to Options > Preferences > System > Updates, and select Alpha from the dropdown menu. Then go to Help > Check for Update, and install the update.
macOS: Go to TheBrain > Preferences > System > Updates and select Alpha from the dropdown menu. Then go to TheBrain > Check for Update, and install the update.
For this specific issue, once you have the new 11.0.75 build installed, please click on
File > Utilities > Add UTF-8 Signature to Notes...
Thank you for working on this. I will try this later.
Achievement of a great thing, is the best reward.
