Ligatures (for example: æ, st, ff etc.) don't work in paint.net; in previous versions you could force it by finding the PresentationFramework.dll file in Windows --> Microsoft.NET --> ... --> WPF and manually changing get_HistoricalLigatures and set_HistoricalLigatures from 'false' to 'true', now this workaround seems to doesn't work anymore - maybe that's because of app using self-containing deployment of .NET? If those changes are made in PresentationFramework.dll file found in paint.net folder, the app crashes. What should I do to get my historical ligatures back?
