Unicode Text not Rendering in mac

[MayuraVerma]

Description

Unicode Kannada text is not rendering correctly in Sublime Text editor.

Steps to reproduce

Create a python test file with below lines.

print('ಕನ್ನಡ ')
print('ನನ್ನನ್ನು', 'ನಿನ್ನನ್ನು', 'ಏನನ್ನು', 'ನನ್ನ')

and run the above print statements

Expected behavior

Expected behavior in sublime Editor

Expected behavior in output window, similar to output in terminal window

Actual behavior

Broken text. Sublime text editor is not applying opentype features 'GSUB' and 'GPOS'. I think the sublime editor is not linking shaping engine.

Harfbuzz shaping engine is preferred over Apple Coretext engine in mac.

Environment

• Build: 3207
• Operating system and version: macOS 10.14.6 (18G95)

Can you provide the literal text in a comment here?

Does Safari render the text properly?

We don't currently have a plan on switching from CoreText to Harfbuzz.

Looks like this on Linux fwiw:

Text: print('ಕನ್ನಡ ') print('ನನ್ನನ್ನು', 'ನಿನ್ನನ್ನು', 'ಏನನ್ನು', 'ನನ್ನ')

Safari has no problem rendering this text.

ಕನ್ನಡ ನನ್ನನ್ನು ನಿನ್ನನ್ನು ನನ್ನ

most Kannada fonts uses

GSUB features: nukt, akhn, rphf, blwf, half, abvs, blws, blws, psts, haln, pres

GPOS features: blwm, dist

Please support these Opentype features.

For me the space towards the end of the first line doesn't show.

@jrappen it’s definitely shaping engine issue

@wbond This appears to be the same issue I reported earlier today on

Any changes to this issue?
