[SOLVED] Noto Color Emoji

[linom]

I am working on Kubuntu 22.04 LTS. It has been observed that with some GUI was not opening due to the Font Type Noto Color Emoji. Disabling this the GUI was successfully opened.
executing the command

# display /usr/share/fonts/truetype/noto/NotoColorEmoji.ttf

Result:
unable to read font `/tmp/magick-8NkJdrn3QxnVQQtkhvTzrKd9bDXlxihn' @ error/annotate.c/RenderFreetype/1481.
non-conforming drawing primitive definition `text' @ error/draw.c/RenderMVGContent/4404.

Opens a blank page without any content.

Does

sudo apt install fonts-noto-color-emoji

have any effect?

[linom]

The package is already installed.

[rab0171610]

So reinstalling it has no effect?

[rab0171610]

Double check System Settings>Appearance>Fonts to make sure Noto Color Emoji is NOT selected as any of the fonts.If it is, change it. If not then at least you have eleminated that as a problem.

Uninstalled and then reinstalled the package but has no effect.

I have already tested it by disabling it and it worked. Concern is whether there is any bug in the NotoColorEmoji.ttf.

Its an emoji font intended to be used by apps that can make use of it, such as Chrome or instant messengers. It is not intended to be enabled as a System wide font.
So you want help seeking out confirmation of a possible bug? I think your problem is solved.

Solution was a work around by disabling. If it is a bug and is currently part of the OS, then it is better to be corrected.

FWIW, display/usr/share/fonts/truetype/noto/NotoColorEmoji.ttf gives the same result, a blank screen, for me. I suspect that this is by design, in that Imagemagick displays ASCII, and the font doesn't have it.

Exactly. If users want to manage this font for some reason they would need to use fontconfig.

But when i execute the same command i.e. NotoColorEmoji.ttf (copied from kubuntu OS) on Debian (jessie), it does open with content on the screen (with all the contents) but with errors displayed on the terminal.

I believe this might affect some GUI (developed in QT) when starting if this font is enabled.
