Can we get a discussion going on the desirability of the "F4 support" patches that Robbbbbert is submitting? I vote "wastes memory and execution time and clutters the drivers for no useful reason", but MESS has never had adult supervision before so I assume they will continue to go in.
In case it's not clear: F4 is a developer aid, not a user feature. It not working for a driver is not considered a problem. Since the drivers the support is being added to all already can decode and display the characters properly there is no developer benefit to them either.
