Check Use Distance Field Alpha and see if it works.
I didn’t fully check it, don’t have access to compiler environment at the moment. But generated font that is imported with that boolean seems to be blurred and “tend” to glow already 
Will check soon and let you know.
Traced DrawText function, enabling distance field should work, as glowing rendered if distance field blend mode is enabled, which IS enabled once Use Distance Field Alpha is set to true.
