Config::Tiny does not work with UTF8 encoded INI with Byte Order Marks

[Outworldz]

Nice module, thanks!
I spotted a glitch on Windows 11 using Strawberry Perl.

Edit:: It appears this is a common problem in Perl core. I was able to workaround it using File::BOM in my Perl code.

UTF-8 chars in a plain ASCII file works in Config::Tiny when I read it as UTF8 without the BOM. If there is a BOM it aborts.

>>Wide character in die at lib/Util.pm line 24.
>>Syntax` error at line 1: '[Data]' at lib/Util.pm line 24.

I have UTF-8 in my INIs. My servers already have BOM's in the file. BOM is the (hexadecimal) byte sequence 0xEF,0xBB,0xBF. They were written using standard Dot Net encoding as UTF-8, which adds the BOM to the beginning.

Dim contents = "[Data]" + vbCrLf
Using outputFile = New StreamWriter(New FileStream(_myINI, FileMode.Create, FileAccess.ReadWrite), Encoding.UTF8)
outputFile.WriteLine(contents)
End Using

I am reading it like this:

# Create an empty config
my $Config = Config::Tiny->new;          
Line 24: $Config = Config::Tiny->read( 'Settings.ini', 'utf8') || die Config::Tiny->errstr; 

Error is:

Wide character in die at lib/Util.pm line 24.
Syntax error at line 1: '[Data]' at lib/Util.pm line 24.

When I edit and save the file without the BOM, it will work, even with UTF-8 in the file later.

I can cure this by not writing the Byte Order Mark at the beginning of the file:

>> Dim utf8WithoutBom = New UTF8Encoding(False)
>>  Using outputFile = New StreamWriter(New FileStream(_myINI, FileMode.Create, FileAccess.ReadWrite), utf8WithoutBom)

Its not possible for me to workaround by cleaning the INI of BOMs as I use other Dot Net INI Nuget modules to manipulate the INI, and always end up back with the BOM issue.

tl;dr
Writing INI as UTF8 fails due to BOM.
Writing INI as UTF8 without a BOM works.
Encoding INI as ASCII and reading it as UTF-8 works. (Encoding.ASCII)
Changing the UTF-8 file by deleting the BOM works, even with UTF-8 in it.
UTF-8 chars in the plain ASCII file works in Config::Tiny when I read it as UTF8 without the BOM.
