Re: Sinhala Font rendering incorrect in Kivy App
Robert
Also bring up the issue on Discord was the right place as that is where the developers are most likely to see it.
The next best thing you can do is create a fork and PR that addresses your issue (these are GitHub terms).
Posting here will not be more effective. Sorry.

I rendered the following text with google Noto Sans Sinhala in kivy app and it is rendered incorrectly. Is Kivy able to render Sinhala characters correctly? As we want to support Sinhala languages in our applications. Please help
Example text Expected output:
පාරිභෝගිකයාKivy application output:This happens in all controls - label and text input and we have tried different ttf files.
Can we get some help here please?
Example code:
from kivy.app import App
from kivy.lang import Builder
kv = """
GridLayout:
id: layout
cols: 1
Label:
text: "Customer"
font_name: "NotoSansSinhala-Regular.ttf"
halign: "center"
"""
class Main(App):
def build(self):
return Builder.load_string(kv)
if name == "main":
main().run()
Font file link: https://fonts.google.com/noto/specimen/Noto+Sans+Sinhala

It looks like you need a reshaping engine that supports Sinhala. I found this reference:
and this: https://github.com/harfbuzz/harfbuzz
Try searching for “Unicode shaper”
