Display of the triangles representing the flows in the model diagram

On my computer, the triangles representing the flows in the model diagram are not displayed.

I don't know where this is coming from, because if I draw these signs directly into R, it works.

tri1 <- c(-0x25BA, -0x25BC, -0x25C4, -0x25B2)
plot(seq_along(tri1), pch = tri1)

tri2 <- -as.hexmode(c("25BA", "25BC", "25C4", "25B2"))
plot(seq_along(tri2), pch = tri2)

On my computer, with the Linux OS (see details below), I tested the interface with two browsers (Firefox and Chromium). The triangles are not displayed.

The sunshine website runs on a Linux server and the triangles are displayed.

On my computer with the Windows OS and the Firefox browser, the triangles are displayed.
