Subject: [PATCH] test(tui_spec): use Unicode in cursor_address test (#30807)

Now that #16425 is fixed, use Unicode again to reduce screen height.
Unfortunately composing chars still can't be used, as it turns out that
composing chars may be missing when sent separately from the base char
at the last char a screen line.

(cherry picked from commit 1189c5ce599ad7172dfde3eb7c0be9c5f8d742f2)
