label = GtkLabel("")
Gtk4.markup(label, """<span size="x-large">A</span>""")

A displays as a small box with four hex digits

I don't know what's wrong but now all the texts display as small box with four hex digits

It works correctly for me on Linux, but I also see the boxes on Windows. Seems likely to be an upstream issue -- I'll try updating Pango_jll.

Updating HarfBuzz_jll, a dependency of Pango_jll and GTK4_jll, fixes this. There is a PR: https://github.com/JuliaPackaging/Yggdrasil/pull/8392

Until that goes through (and a few other PR's that will be necessary to allow that version of HarfBuzz to be used by other JLL's), here is a way to use updated JLL's:

using Pkg

Pkg.add(url="https://github.com/jwahlstrand/libass_jll.jl")
Pkg.add(url="https://github.com/jwahlstrand/Pango_jll.jl")
Pkg.add(url="https://github.com/jwahlstrand/HarfBuzz_jll.jl")
