TemplatePro invalid capitalize result

[Pecaas]

There are some problems with capitalize function and national characters.

Call capitalize of "Křížek přemysl" results in "KřížEk PřEmysl"

In people_table.html in htmlx_templatepro is defined

 <td>{{:person.FirstName|capitalize}}</td>

Capitalize function is implemented in TemplatePro.pas. Instead of defining list of allowed chars it is better for me to define NOTALLOWEDCHARS. Then it works fine. But I do not know all use cases of that function, it can break something on the other place.

function CapitalizeString(const s: string; const CapitalizeFirst: Boolean): string;
const
 // ALLOWEDCHARS = ['a' .. 'z', '_'];
   NOTALLOWEDCHARS = [' '];
var
  index: Integer;
  bCapitalizeNext: Boolean;
begin
  bCapitalizeNext := CapitalizeFirst;
  Result := lowercase(s);
  if Result <> EmptyStr then
  begin
    for index := 1 to Length(Result) do
    begin
      if bCapitalizeNext then
      begin
        Result[index] := UpCase(Result[index]);
        bCapitalizeNext := False;
      end
//      else if not CharInSet(Result[index], ALLOWEDCHARS) then
      else if CharInSet(Result[index], NOTALLOWEDCHARS) then
      begin
        bCapitalizeNext := True;
      end;
    end; // for
  end; // if
end;

Thank you.
