SingleFile Files

Fixes

• Update single-file-core to 1.6.32:
• "Remove unused fonts" no longer drops the unicode-range subsets holding the icon glyphs of fonts that set them through a custom property, such as Font Awesome 7 (.fa-x-twitter { --fa: "\e61b" } behind ::before { content: var(--fa) }). The characters the browser reports having drawn with each family now count in the unicode-range tests, so the icons are no longer rendered with the fallback font.
• The displayed srcset candidate keeps its descriptor when the alternative images are removed. A 240w candidate under sizes="200px" or a 2x candidate was written as a bare src, so a layout reading the intrinsic width of the image drew it larger than on the original page.
• JPEG XL images are named .jxl in self-extracting ZIP archives even when their URL carries no extension, and are extracted as image/jxl instead of application/octet-stream.
