Binding unicode strings to Kepware

Dear community,

from Thingworx I am binding to Kepware tags, reading and writing. This works fine in general but I encountered an issue with special characters. My current example is this string: "Mis.Lác.Cond". When setting this (manually or by code) Kepware receives "Mis.Lác.Cond". In Kepware as well as in Thingworx the tag/property is defined as String.

The only report about this I could find is this article  but this does not help me as Kepware and Thingworx are running on the same machine.

Any help is greatly appreciated.
