These are very simple characters. I tried it looks as close as possible to the original font, feel free to improve it :). I hacked very simple editor, that can help with this task :). I hope somebody could find it useful :) https://github.com/yarda/BMPFontDesigner

[yarda]

I also added empty lines for better readability of the characters table and to group them.

[yarda]

Please do not merge it yet. I used AI to gather list of characters needed, and it seems it forgot "ďĎťŤ" characters which are used e.g. in Czech language. I will add them and update the PR.

[yarda]

Also added "ěĚďĎňŇťŤ" characters. So at least the Czech language, which I am the most interested in, seems 100% covered now.

Some of the added characters:

@yarda Generally all of them look good to me, all fit within the size of the badge. Some of them had to be deformed perhaps to fit in the badge ? But in general, these look good.

[yarda]

I also improved the 'Å' character a bit.

[yarda]

It still isn't complete character set for all European languages alphabet, but I think it is a good start.

@yarda The CI still fails because of the code not being formatted. Just run dart format . in the root of your project and commit the changes.

The recent force push added missing CRs to the empty lines which was probably the cause of the failure. It is according to the output of the dart format . of my added changes. The dart format . also changed formatting of the code I didn't add, but if you need it, I can reformat the whole source file with it and update the PR.

[AsCress]

@yarda Just tried it myself on your branch. It only formats the file that you've changed and removes the empty lines.

NP, I will drop the empty lines. I probably used different dart formatter :)

It seems 2 tests failed, but I don't know why.

Yeah, noticed that as well. However, I may not be able to assist with this, @Jhalakupadhyay might be able to help.

[AsCress]

However, this is good to go once the tests pass.

[adityastic]

Mind updating the tests as well?
