Broken: version: 2.83.6, branch: master, commit date: 2020-09-09 07:32, hash: 8610c69777
Worked: (newest version of Blender that worked as expected)

Short description of error
Trying to write Bangla text in Blender for making a motion graphics animation but Blender is unable to help me with that I can't write Bangla in Blender properly. Tried using Bangla fonts but didn't worked out for me after importing Bangla text when I press tab and write anything it's invisible also if I paste Bangla text it is invisible.

Exact steps for others to reproduce the error
Download Bangla font and Avro keyboard (it is used for phonetic Bangla writing) from online and open both Blender and Avro Keyboard then create General project and then add a text object then in from avro select Bangla as typing language also you have to load the Bangla font you downloaded from online.

This is confirmed.

I would mark this as a known issue and add it to the documentation.

Below is an example using Windows10 Unicode font NirmalaUI in Blender (without script processing) and in MS Word (with Uniscribe script processing).

It may be possible with other Bengali fonts that are not encoded in Unicode.

Unicode fonts for South Asian languages (Bangla etc) need support from the type renderer to process the glyphs.

I don't think that the freetype type library/renderer in Blender supports these languages properly as it needs additional text processing using a library like Pango for instance: https://pango.gnome.org/

Hopefully someone else can help here.

Confirmed that our current droid sans UI font does not contain any glyphs in U+0980 - U+09FF (Bangla) or U+011480 - U+0114df (Tirhuta). Also tried loading a font with those glyphs (NotoSansBengali) into Properties / Text Data / Font and was unable to view any text objects with those characters.

We're getting closer.

We are now enabling IME for non-CJK languages. With the following patch applied - https://developer.blender.org/D12622 - I can then change the UI language to NotoSansBengaliUI-Regular.ttf. This font only contains Bengali characters without any others including latin, but the patch does fallback to our large font.

Afterward I can enter text in edit boxes. We'd need to do some some work with the 3D text input though, but copying and pasting text does work there.

Note that we now include a complete Bengali font as of {e9bd6abde37c}
