Cyrillic characters display as ?????? in Postmania web interface (Visual Paradigm Server 18.0)

Dear Visual Paradigm Support Team,

We are experiencing an issue with Cyrillic character encoding in the Postmania web interface of our Visual Paradigm Server installation.

Problem Description:
When a team member creates a commit with a merge request containing Cyrillic text (Russian language), the approver receives an email notification correctly. However, when opening the corresponding page in the Postmania web interface (http://<server>:1999), all Cyrillic characters are displayed as ?????? (question marks).

Environment Details:

  • Product: Visual Paradigm Server

  • Version: 18.0

  • Build Number: 20260311

  • OS: Windows Server 2022

  • Java Runtime: Eclipse Temurin 21 (21+35-LTS)

  • Database: Embedded

  • Server Port: 1999

  • Locale: ru-RU (user), en-US (system)

Relevant System Properties (from admin.jsp#systemtools):

file.encoding=UTF-8
sun.jnu.encoding=Cp1252
native.encoding=Cp1252
user.language=en
user.country=US
user.language.format=ru
user.country.format=RU

Expected Behavior:
Cyrillic text should display correctly in the Postmania web interface, matching the content show.

Request:
Please advise on the correct configuration steps to ensure proper handling for Cyrillic characters in the Postmania web component.
