# sboxes Keep in mind, the macro utils.tmac sources sboxes.tmac, but that macro is exclusive to groff v1.23.0, which is not present on Debian 12. Compiling it from source is really easy though, thanks to GNU's coding standards. # Custom fonts & glyphs In order to install a font with U+2112 '_Laplace transform_' glyph, search in your system for fonts with that glyph, and create a groff font with afmtodit. ```shell grep -r '2112' /usr/share/fonts/* 2>/dev/null afmtodit -e text.enc -i0 -m path-to-font.afm /usr/share/groff/current/font/devpdf/map/textmap NAME mkdir -p /usr/share/groff/site-font/devpdf/ # Create this directory if not already present mv NAME /usr/share/groff/site-font/devpdf/ ```
