If you have integrated SCOM 2012 and SCVMM 2012 and are using the PRO management packs you may have noticed some groups containing Chinese characters.
In an English-language version of Microsoft System Center 2012, you connect Virtual Machine Manager (VMM) to Operations Manager. However, group names in the Performance and Resource Optimization (PRO) management packs contain Chinese characters.
Cause: This behavior occurs because the LanguageCode option for the management group is not set in the Operations Manager database. Therefore, when a management pack contains multiple languages, its display names appear in the last language that is included.
Microsoft has published a KB article with the solution to this issue.
