As already noted in feature request #387 mocca performs validation of the input data for the secure viewer.

Mocca complies to the minimum implementation requirements of the security layer specification. Therefore only charset ranges listed in the minimum requirements are supported (see http://www.buergerkarte.at/konzept/securitylayer/spezifikation/aktuell/m...).

CreateXMLSignatureRequests referencing data containing characters not being supported are rejected. The security layer specification defines that requests referencing character data that cannot be displayed have to be rejected.

Since documents often contain special characters like bullets for instance, there should be another way to handle those requests without rejecting them on the one hand and without violating the specification on the other hand.

One solution could be that the secure viewer shows a note saying that the text contains characters that cannot be shown securely providing the user a choice to either reject the request or to save the text locally in order to open it with an appropriate external viewer.

Note: Refer to feature request #387 which describes a related problem.
