Non-latin symbols support

[vania-pooh]

With current images we get tofu instead of Chinese symbols.

[ikuznechikova]

I have a problem not only with Chinese, but also with Korean, Chinese, Arabic symbols. Reproduced in all versions Selenoid(firefox, chrome, opera)

[vania-pooh]

Ok, will take a look during the weekend.

Found an easy solution: need to install one more fonts package fonts-noto-cjk. The only issue is - installing this package adds 100 Mb of fonts. Investigating how to obtain the same result spending less disk space.

[vania-pooh]

An alternative Chinese fonts are in package fonts-wqy-zenhei (17 Mb).

[vania-pooh]

Created 2 test images: vaniapooh/firefox:54.0_noto and vaniapooh/firefox:54.0_zenhei.

Ivan, thank you! Now that's better, but add a display of Thai symbols, please.

[vania-pooh]

@ikuznechikova thai still does not work even with noto image?

[ikuznechikova]

Unfortunately, thai symbols doesn't work neither in noto nor in zenhei images. See screenshot above.

[vania-pooh]

Ok, will check that.

@ikuznechikova In order to support Thai we need to install fonts-thai-tlwg-ttf package (adds 8 megabytes to image). Please test with the following image: vaniapooh/firefox:54.0_zenhei_thai - it contains both Chinese and Thai support.

[ikuznechikova]

@vania-pooh , thank you very much! Now all the necessary symbols (Chinese, Thai, Korean) are displayed in the browser of the image: vaniapooh/firefox:54.0_zenhei_thai

[vania-pooh]

Good. Will need to apply these changes to all images.

[trysh]

thank you !
When to apply these changes to all images (selenoid/chrome selenoid/firefox ...)?

[vania-pooh]

We are currently thinking about one more improvement related to logging. Will update this issue when this is done. Updating all 100+ images is a lot of work and will cause users to redownload a lot of stuff. We should think a bit more before doing such changes.

[vania-pooh]

While waiting for this issue to be fixed here is an example Dockerfile how to customize fonts:

FROM selenoid/vnc:firefox_54.0

RUN \
    apt-get update && \
    apt-get -y --no-install-recommends install fonts-wqy-zenhei fonts-thai-tlwg-ttf && \
    apt-get clean && \
    rm -Rf /tmp/*

[vania-pooh]

Possible Japanese font packages: fonts-ipafont-mincho fonts-ipafont-gothic.

[vania-pooh]

Pushed an example image of what I would like to add to all browser images - vaniapooh/firefox:56.0. It includes fonts as well as encodings. Please test whether fonts are OK.

[ikuznechikova]

@vania-pooh
It was checked the display of non-Latin (Korean, Thai, Chinese, Japanese) symbols in the image vaniapooh/firefox:56.0, the test ok

[vania-pooh]

@ikuznechikova ok, will prepare more images.

[arslanbekov]

@vania-pooh hi, no news? We are really looking forward to :)

[vania-pooh]

@arslanbekov will start rebuilding today. Which browsers are more important? I could e.g. first of all rebuild all Chrome or Firefox images.

[arslanbekov]

The most necessary — Chrome

[vania-pooh]

Agreed.

[vania-pooh]

Forgot to add hindi fonts. Possible solution - fonts-deva. Test page: https://hi.wikipedia.org/wiki/%E0%A4%AE%E0%A5%81%E0%A4%96%E0%A4%AA%E0%A5%83%E0%A4%B7%E0%A5%8D%E0%A4%A0

[vania-pooh]

After a month of intensive work this is finally fixed. All images are supporting new fonts and video recording.
