Support more scripts with Noto fonts

[mapmeld]

I've seen an improvement to how Southeast Asian script labels are rendered on OpenStreetMap.org using the upgraded Mapnik (and possibly this recently merged PR to their carto style: gravitystorm/openstreetmap-carto#2349 )

Would it be possible for the HOT style to use Noto fonts, too?

Sounds good! I'll have a deeper look :)

[yohanboniface]

Just has a quick look: Noto only has four styles (regular, italic, bold, bold italic).
The issue is that we are using semi-bold a lot, so this needs a bit of design decision whether to move down to regular or up to bold for each usage.
I'll try to have a new look.

The next version of Noto is in development and will have support for various weights and widths: https://github.com/googlei18n/noto-fonts/blob/master/FAQ.md#what-are-googles-plans-for-noto-so-called-phase-3 There is an alpha version available yet: https://github.com/googlei18n/noto-fonts-alpha Not sure when the final Noto Phase III will be released…

Thanks for the info!
I'll digg into this, would love to support Noto, which as broader alphabets support.

Let me know if you have further questions (regarding the code for Noto in openstreetmap-carto)…

[sommerluk]

With notofonts/noto-fonts#967 now new Noto version with various weights is released at https://github.com/googlei18n/noto-fonts (dictionaries “hinted” and “unhinted”).

Are you sure #293 is related? Does it have to do with Noto fonts? Isn't just showing empty boxes worse than showing the character, but just in a different font?

[jidanni]

As you see, every single Chinese character is gone

And as this area's official language is Chinese, wouldn't that impede any rescue operations etc. making this a critical bug?

[jidanni]

On the Korean example at the top of this bug page, there is plenty of Korean still visible. On my Chinese example every single last character is gone.

[mapmeld]

If it helps to identify the bug - Chinese characters are still visible on zoom-11 and broken on zoom-12

OK, sorry, seems really a new bug, reopening #293
