NAG breaks spacing ? #415

Open braoult opened 1 year ago

braoult commented 1 year ago

I found the issue on some of my games, and was able to reproduce it on configurator:

nag

To reproduce: To do that, just choose Evergreen (no boards) game in Configurator, and add the $15 (⩱) NAG after one move (in example above, it was after 4... Bxb4). The space above the line becomes doubled.

I believe it could be a font issue, if the NAG character is not found... I have no idea on what should be done.

Maybe linked (on Firefox 109.0 64 bits, Xubuntu 22.10) to two fonts errors that I noticed in console ?

font-error

EDIT: Some other NAGS (like $16, ±) do not have this issue. Having a look further in Firefox, selecting the character shows the fonts used :

±: CA Chess
⩱: STIXMath-Regular

I tried to reproduce your error, but failed. I tried with the following browsers:

Firefox 109.0.1 (64-Bit) (very similar to your setup, using Ubuntu 22.04.1 LTS)
Chrome latest (Version 109.0.5414.119 (Official Build) (64-bit))
Chromium latest
Vivaldi latest (the 2 are Chromium based)

and of course no error in the console (only Firefox shows that 2 errors(. So sorry, what do I have to reproduce your error then? The following is the screenshot from Firefox.

I tried on my wife computer (Ubuntu 22.04, FF 105.0.1). I did not install anything fancy on that one, and I have the same issue : pgnviewer-mac

Looking at the ⩱, is uses also the STIXMath-Regular font.

I made different tests:

Ubuntu 22.10 : Chromium and Brave browser: display OK, font used for ⩱: CAChess.
Android: Firefox: display OK (I don't know which font is used, nor if error shown in previous messages appears).

As display is fine on your own Firefox/Ubuntu, is it possible you have installed a copy of CAChess font on your system ?

You were right, the font is installed locally. I try to understand what is included in the distribution (I compiled somehow a file CAChess-min.woff, which seems to be wrong), and how to fix it.

Doing the same locally, I see the following information:

which is the font I want to use
is shown when looking at the rendered font.

I have no idea what is going wrong here. When I disable / deinstall the rendered font, I will get at some point in time the same error, I suspect. Not sure how to proceed here. I cannot understand why the provided font is not used. But perhaps the error message indicates just that.

I will do the following:

Use locally a different font file when building the software.
Running it locally then to see if that different font is then used instead.
Try to understand what the error message means ...
