Description

Using Bootstrap Icons from HTML means one can use nice readable names, whereas using them in CSS means authors have to deal with cryptic Unicode codes like \F4CA. It would be lovely if the CSS file also set CSS variables for all icons, so they can be also used with nice readable names like var(--bi-pencil-square).

Research direction
The issue requests adding CSS custom properties for each Bootstrap icon to allow usage like var( bi pencil square) instead of Unicode escapes. The current CSS file (bootstrap icons.css) defines icons via ::before with content. Implementation would involve extracting icon names and their Unicode values from the source (e.g., from font files or a mapping script) and generating corresponding CSS variables. Check the existing build scripts (e.g., in package.json or related tools) to see how the CSS is generated. The issue has one comment; review it for maintainer feedback or guidance.
