Hi Dave, thank you for this perfect answer, much appreciated. Worked for me.

I had the exact same issue now. Without any particular reason for it to start, or in other words, I did not make any changes to the project file. Your advice set me on the right path. But in Notepad it did NOT show any offending characters, so I copied that problem line of code, then pasted it into another Notepad. Doing so removed the illegal char, then copied the new line and replaced the old line. The offending char was now gone and Delphi compiled again.

Google Play store has notified devices using Android 10 that my app is not compatible with their devices. I am using Delphi 10.3 with Update 3 and AndroidSDK-2525_20.0.36039.7899 with API 26. If I have to upgrade my Delphi to a later SDK, please kindly post a link on steps how to do that.
