Dotted Circle with Combining Diacritics on Keycap

(@Martin, apologies I did not see your comment on this post – best to open a new topic rather than pick up a very old topic, as we’re more likely to see the notification.)

With Keyman Developer 17, we have a pathway for improving this situation, but it is a little technical: &displayMap.

I changed the font with andika and I find that it displays diacritics well, since I use AndikaAfr. I wanted to know if this caused any other display problems or if it displayed all the special characters?
then in my help page it displays the same chosen as before no dotted circle, as in the screenshot


This is the font we currently have in the CSS file
font-face {
font-family: CharisSILWeb;
font-weight: normal;
font-style: normal;
src: url(“https://fonts.languagetechnology.org/fonts/sil/charissil/web/CharisSIL-Regular.woff2”) format(“woff2”);
}
body {
font-family: ‘Charis SIL’, CharisSILWeb, Gentium, serif;
}
but it doesn’t display this
