There have been fixes for that one, specifically recent qemu will look
at modifier state in addition to the keysym when looking up the keycode,
because some keymaps can generate the same keysym with different key
combinations, and most of the time they have different modifier state.

In this specific case the us kbd key generates '|' with shift while the
105th key of i18n kbds generates '|' with altgr, so it should actually
improve things.

So, try upgrade qemu.

No.  It's ui/keymaps.c.  Keymaps are in pc-bios/keymaps/, generated by
qemu-keymap.c.
