Dear ven, that is fantastic, thank you so much. I have made a ticket for this and we will add the updated font.
Normally we use Google’s Noto fonts for scripts not covered by our main font, Skolar. While Noto may not be the best designed font in each and every case, it has consistent style and metrics, so we can use many different scripts on the same site. Another advantage of the Noto fonts is that they come in many different styles—serif and sans serif, different weights, etc.—allowing for complex typography.
The extra 15 characters have not been added to Noto, but the issue is noted, and they are planned to be added in “Phase IV” of their development cycle.
This will take some time, however. They are currently 60% finished with Phase II, so we can safely say that Phase IV will be some years away.
So what I am wondering is, might it be possible for you to add the extra 15 characters to Noto? The license allows reuse with modification, so that is not a problem.
I have compared the metrics of Lanexang Mon4 (red) and Noto (blue.
Attached file for your references. The fonts Noto family allow to use only “AS IS”. Also, each font family they have different style & kearning, so after add the characters it may need some adjustment to match all characters, this issue it will be time consuming.
So, the easy way is to use my font for now until the font Noto available in the future, then you just switch it to the name of the Noto font.
This is all Lao glyphs of font LanxangMon4 while replaced to the Noto serif lao blocks. The kearning is working fine with this block. And I can make the name as “Serif Lao”. Is this what you looking for?
Yes, the metrics is of Noto possibility it should still and only the name of new 15 characters I follow by unicode12. The 3 fonts extension otf, woff, woff2 are in ziped file, test it out and please let me know the feedback.
