But they do it oh so very wrong.
Kerning is the spacing between individual letterforms, while letter-spacing or tracking is the overall spacing of characters. Letter-spacing is what's the issue here.

Neither RMSDK nor the default renderer do anything when I set letter-spacing in CSS.

This works fine in Calibre, Thorium, Sigil and Apple Books:
Code:
CSS:
.spacing {
  letter-spacing:0.5em;
  }

HTML:
<span class="spacing">text</span>
(see attached screenshot –*it's applied to the word "consectetuer")

Both renderers seem to apply kerning by default. In the default renderer it can be deactivated with CSS, in RMSDK it can't. Deactivating kerning in the default renderer doesn't fix my problem. It's definitely a letter-spacing issue.

They responded to that list, for some of them (e.g. Missing sentences at chapter ends), they mentioned that these issues would be "known to the software developers and a fix is work in progress". For incorrect letter spacing, they mentioned that they "relayed that feedback to the developers".

I'd suggest others do the same - I guess they are unlikely to fix that issue if I'm the only one complaining .
So I'm not the only one noticing this issue. I also sent them a complaint.
