ActiveRecord can't store unicode data correctly

[Shaahin Ashayeri]

Hello everyone, 😍
ActiveRecord can't store unicode data correctly. I am using activerecord_showcase sample and trying to store some unicode text in database but data will be appear like ????? in database table! also 'CharacterSet=UTF8' parameter added into connection but wrong result appears again. I am using firebird3 and DMVC carbon edition.
✳️For reproduce problem you can try to store this string:
'این یک تست است!'
1️⃣ Update 1: this problem appears when English(United States) selected in this path in windows 10:
Control Panel>Region>Administrative>Change system locale...
2️⃣ Update 2: When Persian(Iran) selected from previous path then It works correctly. Is It possible to configure DMVC's ActiveRecord to working in any situations without changing Windows settings?
3️⃣ Update 3: bug solved 🙂
For solving this problem follow below steps:

1. In MVCFramework.ActiveRecord.pas unit.
   ❌change below section:
   ftUnknown, ftString, ftWideString:
   begin
   aParam.AsString := aValue.AsString;
   end;
   ✅ To this:
   case aParam.DataType of
   ftUnknown, ftString, ftWideString:
   begin
   aParam.AsWideString := aValue.AsString;
   end;
2. And in MVCFramework.ActiveRecord.pas unit.
   ❌change below section:
   {$IF Defined(SeattleOrBetter)}
   tkWideString:
   begin
   aParam.AsString := aValue.AsString;
   end;
   {$ENDIF}
   ✅ To this:
   {$IF Defined(SeattleOrBetter)}
   tkWideString:
   begin
   aParam.AsWideString := aValue.AsString;
   end;
   {$ENDIF}
   Special thanks for DMVC Framework team and specialy for Daniele Teti
