i18n text in flowable admin application

Hello. This issue is from forum.
I have a diagram where task node name is not in english, in fact it is in russian.
It is not displayed in flowable admin application properly. May be it is a encoding issue.
My BPMN 2.0 diagram attached.
In addition here is a link to forum issue http://forum.flowable.org/t/flowable-admin-i18n/342;
