What is the issue? There are many people that can help you on different topics. Perhaps it would be best to ask your question on help.openstreetmap.org
The issue is a considerable one. Some had done with Private font, not with standard, truly and fully-compliant Unicode font, thus needs to be tackled from Admin-level and bulk-remedial to be implemented.
Note however that a number of the more complicated languages can’t be properly tackled until we upgrade mapnik 3 with harfbuzz support (mapnik 3 should hopefully be release in the near future, but there will likely be a delay before we can upgrade to it).

If you mean that local names are not being rendered in an appropriate font on the map then https://github.com/gravitystorm/openstreetmap-carto/issues is the place to report it.

I corrected some and the result : correct display. So, as it is, OK for this language. Thanks for the link.
