Include fonts in themes (standalone build for `theme-library`)

[abs-lme]

Hi!

First of all, I am not sure if this is a bug or a feature request.

Is your feature request related to a problem? Please describe.

I found that when creating a custom theme (using type theme-library) it builds all the CSS files but the theme is not really usable as the font files are not contained in the build result.

CheckBox tick marks and Select arrows are not properly displayed in the theme:

The reason is that the fonts (especially the SAP-icons) are not loaded.

Further analysis

I made a MWE. It just contains a theme-library project with framework SAPUI5 1.104.2 and 5 dependent libraries (sap.m, sap.ui.core, sap.ui.layout, sap.ui.unified, themelib_sap_horizon).

When running the app with parameter sap-ui-theme=custom_horizon@/theme:

• it properly loads CSS files from /theme/UI5/sap/ui/core/themes/custom_horizon/library.css?version=1.104.0&sap-ui-dist-version=1.104.2 and similar URLs
• it tries to load the fonts from /theme/UI5/sap/ui/core/themes/sap_horizon/fonts/72-Bold.woff2, /theme/UI5/sap/ui/core/themes/sap_horizon/fonts/SAP-icons.woff2 and others, but fails with error 404

I checked the dist folder and found that it only contains css, but no font files. For testing I copied the requested font files to the corresponding folders and re-built and re-deployed the theme. It worked without any 404s.

Describe the solution you'd like

It would be nice to have the possibility to create a self-contained theme, like the self-contained mode works for apps.

Additional information

The theme is deployed to a CF HTML5 repository (but it would be the same when deploying to another custom server).

Thanks a lot!
