This font [fontname] contains MarkGlyphSets - Not tested yet

[mhgolij]

In Arabic, when we use diacritics in words, the following error occurs: This font [fontname] contains MarkGlyphSets - Not tested yet. By commenting out the following code in the Otl file at line 4489:

if ($flag & 0x0010) {
			throw new \Mpdf\MpdfException("This font [" . $this->fontkey . "] contains MarkGlyphSets - Not tested yet");
			// Change also in ttfontsuni.php
			if ($MarkFilteringSet == '') {
				throw new \Mpdf\MpdfException("This font [" . $this->fontkey . "] contains MarkGlyphSets - but MarkFilteringSet not set");
			}
			$str = $this->MarkGlyphSets[$MarkFilteringSet];
		} 

The problem is solved. What is the solution?
