You also shouldn't paste blackboard characters as you did in your example.
Instead you should use \blackboard command -> check wiki. You will have to place it within a math environment though, so it might be wiser to read into "natural TABLES". -> also check wiki.
For example: \startformula {\blackboard Hello World} \stopformula or \startformula {\blackboard R} \stopformula Greets, Seba Am 29.05.2016 um 18:38 schrieb Hans Åberg:
