Warning: Unable to open font (...)

I cannot add label in Cyrillic, such as "Кухня":

It's impossible using default font, but when you use a font that supports latin characters everything works:

[leva3000]

Thanks, just need to know all of my font available. I am using HA in docker.

[PiotrMachowski]

Here you have a command that should retrieve all available fonts: https://github.com/PiotrMachowski/Home-Assistant-custom-components-Xiaomi-Cloud-Map-Extractor#texts-configuration

On RPi I have another error:

[PiotrMachowski]

Can you check which version of pillow/PIL you have?

pip3 list

[leva3000]

I am trying to figure out how deps are installed for HA in docker... Which python is used and where to run the command.

[leva3000]

Pillow 7.2.0

[leva3000]

I am trying to run the next:

apk add --no-cache g++ freetype-dev jpeg-dev
pip uninstall pillow
pip install --no-cache-dir pillow

to make sure pillow will be compiled with libfreetype. I am not sure if this will be a persistent solution for HA in docker.

[leva3000]

It looks like no fonts preinstalled in homeassistant docker image

[PiotrMachowski]

I will try to find a way to attach a font file

[leva3000]

Solution for me was to jump inside HA container and run the next commands:

apk add --no-cache g++ freetype-dev jpeg-dev
pip uninstall pillow
pip install --no-cache-dir pillow
apk add font-noto

and use NotoSansDisplay-Light.ttf font.

BTW it will be nice to choose TTF file stored somewhere in the config folder.

[leva3000]

[PiotrMachowski]

Using TTF stored in a config is much better, as it doesn't require manual changes after every HA update. I will check if it is possible

[leva3000]

But there is still an issue with Pillow installed(compiled during installation) without libfreetype. I don't know if there is any solution for that. That how homeassistant processing requirements, looks like no options to control that. So I still have to run the command after every update of HA.

[8osman]

I've hit the same problem, unfortunately my understanding is too limited to follow the instructions above.

I'm left with "ImportError: The _imagingft C module is not installed"

My home assistant is also installed within docker.

Thanks for the great work, really looking forward to being able to utilise this! :-)

[leva3000]

After HA was updated to 0.116.2 I cannot fix the issue with the above commands. Every time I see The _imagingft C module is not installed error.

[XxCabbyoO]

I have the same error. So there is currently no solution to fix the Problem?

RPI4

[PiotrMachowski]

Unfortunately I haven't found a solution yet

[PiotrMachowski]

I have added handling to errors thrown during fonts loading.

[Nicols07]

I use HA on Docker with my NAS Synology. No fonts TTF on Synology...

it's Ok wihout font: "FreeSans.ttf" but i can't change the font_size...

texts:
      - text: "Room 1"
        x: 25
        y: 25
        color: [125, 20, 213]
        font_size: 100
      - text: "Room 2"
        x: 25
        y: 75
        color: [125, 20, 213, 127]
        font_size: 10

[PiotrMachowski]

@Nicols07 unfortunately it's not possible to change size for a default font

Hi! I came over this issue when troubleshooting a similar issue with one of my own integrations. Not sure if it helps for this case, but I found a workaround by using bitmap fonts and then converting to PIL-fonts. Quite cumbersome solution, but it works better in my case. More info here if you're interested.
