I created a new module of the type «custom». «Show Title» is set to «Yes». Header tag is «h3». My title is «Über uns» but is displayed as «Uber uns» (without dots). See the Base-2A Module on my website.
For testing purposes, I added the same text «Über uns» as «h3» title within the module content. In this case, the German umlauts are displayed ok.
Thank you and kind regards
