FMXInno - Windows Fluent Design Installer UI for Inno

[Fak Eid]

When trying to create an .ini file for setting config of my installer using:
INI_Maker: FNewINI;
INI_Maker.FCreate(ExpandConstant('{src}\Game\Insta ller.ini'));

it is creating the file in UTF-8 with BOM which is messing with Inno Compiler and not producing the desired result. How can I have FNewINI to create the file in UTF-8 format.

In case when the main section say [Execs] doesn't exists and we create the SubSection using FNewINI:

INI_Maker.WriteSubString('Execs', 'AppExe'+IntToStr(j), 'Name', ExeEdit[i].GetText);
INI_Maker.WriteSubString('Execs', 'AppExe'+IntToStr(j), 'Filepath', ExeEdit[i+1].GetText);
INI_Maker.WriteSubString('Execs', 'AppExe'+IntToStr(j), 'Parameters', ExeEdit[i+2].GetText);

It does not create the main section.
Desired output should be:

[Execs]
[Execs\AppExe1]
Name=Horizon Forbidden West
Filepath=HorizonForbiddenWest.exe
Parameters=--fullscreen

It is like this instead:

[Execs\AppExe1]
Name=Horizon Forbidden West
Filepath=HorizonForbiddenWest.exe
Parameters=--fullscreen
