## Run
The popup needs one to four scalable font files. No fonts are bundled.
`run.sh` uses installed DejaVu, Jigmo, or Noto CJK fonts when available, or
accepts explicit files in fallback order:
The popup needs one to four font files. No fonts are bundled. Each file is
validated and registered with Pango as an application font. Pango shapes the
complete string and chooses glyph fallback from those fonts and the normal
system fonts; command-line file order is not an exact per-glyph fallback
contract.
`run.sh` uses installed Noto Color Emoji, DejaVu, Jigmo, or Noto CJK fonts when
available, or accepts explicit files. Supply a color emoji font such as Noto
Color Emoji to render emoji in color:
```sh
./run.sh
./run.sh /path/to/primary.ttf /path/to/fallback.ttc
```
The popup renderer requires Pango/PangoCairo 1.56 or newer and Cairo 1.18 or
newer.
The script starts the daemon and, when `DISPLAY` is set, the XIM frontend. It
restarts any existing `strans` processes owned by the current user.
