AceConfig-3.0 own font file needed

[Platine]

I need to display text in national language. How can I set my own font file with diacritics of my language?

local LibStub = LibStub;
local AceConfigRegistry = LibStub("AceConfigRegistry-3.0");
local AceConfigDialog = LibStub("AceConfigDialog-3.0");
local AceGUI = LibStub("AceGUI-3.0");
 
local My_Font = "Interface\\AddOns\\Test\\frizquadratatt_pl.ttf"; 
 
 
-------------------------------------------------------------------------------------------------------------------
 
local testOptionsGroup =  {
   type = "group",
   order = 10,
   name = "Test",        -- name of tab #1
   get = function(info)
      return info;
   end,
   set = function(info, value)
      value = info;
   end,
   args = {
        generalMainHeaderQS = { order = 10, type = "header", name = "Test section", },       -- header of section 1
      
      activateTestOption1 = {
         type = "toggle", order = 20, name = "Zażółć gęślą jaźń", desc = "To jest testowy opis tej opcji", width = "double",
         get = function(info)
            return true;
         end,
         set = function(info, value)
            wynik = value;
         end,
         },
         
      },
   };

--SETTING OF OPTIONS
-----------------------------------------
local options = {
   type = "group",
   args = {
      general = { type = "group", name = " Test header   ver. 123" , childGroups = "tab",
         get = function(info) return info end,
         set = function(info, value)
            info = value;
         end,
         args = {
            testOptionsGrp = testOptionsGroup,
            },
         },
      },
   };
 
-----------------------------------------------------------------------------------------------------------------
 
-- general Test configuration
AceConfigRegistry:RegisterOptionsTable("Test", options.args.general);
 
Test_OptionFrame = AceConfigDialog:AddToBlizOptions("Test");
InterfaceOptionsFrame_OpenToCategory(Test_OptionFrame);

I can see that this is a difficult topic.
I decided to use a not so sophisticated solution by modifying the Ace libraries directly:

AceGUIWidget-Heading.lua
Line 28: self.label:SetFont(My_Font, 13);

AceGUIWidget-CheckBox.lua
Line 193: self.text:SetFont(My_Font, 13);

AceConfigDialog-3.0.lua
Line 512: _G[tooltip:GetName().."TextLeft1"]:SetFont(My_Font, 13);
Line 519: _G[tooltip:GetName().."TextLeft2"]:SetFont(My_Font, 13);
