ReloadCharFilters()

Reloads the factory list. Changes to the factories are visible after the method ends, all iterators (AvailableCharFilters,...) stay consistent.

NOTE: Only new factories are added, existing ones are never removed or replaced.

This method is expensive and should only be called for discovery of new factories on the given classpath/classloader!

Declaration
public static void ReloadCharFilters()
