 If your app does not allow you to control stylistic sets, try generating new font file that has them built-in:

+  Depending on your needs this tool might be sufficient, but it only supports fixed single character replacements.
+  It for example does not support `>=` `<=` from `ss02`, `&&` from `ss03`, `<$` `<$>` `$>` from `ss04`,
+  and `==` `===` `!=` `!==` from `ss08`.
+  It also does not support context-sensitive stylistic sets like the thin escaping backslash from `ss06`.

+  Depending on your needs this tool might be sufficient. It supports more than the previous tool,
+  but still not everything this font uses.
+  It for example does not support `<$` `<$>` `$>` from `ss04`.
+  Besides that, it makes the Font version `1.000` and also removes all other metadata like copyright, licence and so on.
+
+- The best option is the build of this project itself. It needs some setup like installing Python and some
+  modules, or having a Docker daemon running, or using GitHub Actions for it, and it needs much longer than
+  the previous options. But the end result properly supports all stylistic sets and preserves the metadata.
+  Additionally, you can build from the latest state and thus can get new features (but of course also new
+  bugs) that were implemented since the last release.
+  The `README` contains up-to-date information on how to build the font with wanted stylistic sets baked in.
