Some bitmap font glyph substitutes are erroneous or missing

Some letters appears as "?", some of them are á, ã, õ, and upper case letters with things like "´", just have the letter and not the thing on the top (I forgot how to say acentuação in english)

• The problem just happens on OpenMW not in vanilla morrowind
• My operating system is Manjaro Linux, but in Windows 10 has the same bug
• OpenMW 0.48.0
• GOG Version, it's a font problem so, doesn't matter what mods i'm using becuase it happens even if I don't use mods and just the translation mod
• I'm using mods but it happens even if I don't use them
• Use letters such as ã, á, É on the dialogs
• Letters appear correctly
• No
• settings.cfg
• Everywhere that has these letters on dialogue (probably other letters have the same issue but I have to test it)
