Foreign letters not showing in label after export to HTML

Godot Version 4.4

in godot editor all symbols are displayed (such as: ў ң ө 秒 告 时), but after exporting to html they are replaced by rectangles with 4 characters “0456” “04A3” “04E9”

while after export for Windows all symbols are displayed correctly

I tried to remove my font and leave the one built into Godot, but the symbols still change to rectangles.
