Description Thomas Friedrichsmeier 2026-01-18 09:42:27 UTC

Graphics text misalignment with some symbols.

Try the following code example with RK() and grDevices::X11() devices:
  plot(1, 1, sub="☀️ ☀️\nx x\n௵ ௵")

For the RK()-device the first pair of symbols is off-center, somehow.

First found in rkward 0.8.2, but probably the issue has been around for much longer.
