The translation tool supports both direct input of special characters (æ, þ, ð) and alternative typing methods. If you can’t type these characters directly, you can use .ae for æ, .th for þ, and .dh for ð. For example, you can type ‘of.thrycca.th’ instead of ‘ofþryccaþ’. The system automatically converts these alternatives to the proper Old English characters during translation.
