[FR] Cross-platform font automatic mapping

[mokeyish]

This issue is unique.

• [X] I have used the search tool and did not find an issue describing my idea.

Your idea.

Fonts on different platforms are different. Some fonts are not available, or display abnormally, and the effect is not good.

I hope to add a global font mapping that can be mapped to a specified font based on the font name.

Hello @mokeyish! Thanks for your idea, but we are already using this scheme. If the system does not have a specific font, then we replace it with another one that is most suitable not only by name, but also by font metrics

Thanks for your reply. But I hopefully this can be configured manually.

This is the automatically selected font:

This is the desired font:

@mokeyish I don't quite understand what actions you are doing to reproduce the problem. Can you tell us in more detail what you expect and at what stages?

[mokeyish]

@TatianaKirillova The font is set on Windows, but macOS does not have this font. Just like what you said, onlyoffice will automatically find a suitable font, but this font still does not display well. So I hope there is a place where I can configure it globally, fontA => fontB mapping.

For example, the following configuration

{
    "fontMappings": {
        "Calibri": "思源宋体",
        // other mappings ...
    }
}

When onlyoffice wants to use the calibri font, it is forced to switch to 思源宋体.

BTW, @TatianaKirillova do you have documentation on how to contribute to this project? For example, how to start debugging. I tried looking for npm run dev in package.json, but couldn't find it.
