Current Humanitarian layer doesn't support Bengali font and because of this Bengali text in the map does not render correctly (Example). Standard, Cycle Map, Transport Map layer already support Bengali font & they currently displayed Bengali text.
I am requesting for adding a Bengali font. You can use NotoSansBengali font which is under the SIL Open Font License (OFL). There is other font like Siyam Rupali which is also under free licence.
