Summary0009794: Base Info Server Capabilities 006 produces a rendom string that very often containes '$'-character.
Description

Our Device publishes string variables defined in a IEC 61131-3 PLC program via OPC-UA.
A user might want to use the '$' escape character to refer to white space or control characters, as he is used to set value of PLC variables this way.
Does OPC-UA supports character escaping, when setting string variables?

If so, a string containing escape characters (such as '$') might be invalid input in cases where the escape character is followed by any random character.

OPC does not define escape character rules for strings. If a model want to have escape characters for string , it should define a sub-type of String with appropriate rules.
