Hi, problem is in method PdfFontMetricsFreetype::GetWidthArray when using Windows-1250 encoding or any other diffrence encoding. For example lettr 'ě' has code 236 in windows-1250 but the same code in latin1 has 'ì' which is loaded by method FT_Load_Char in GetWidthArray, so wrong width is inserted to array. In my patch is loaded unicode value of character from encoding object and according to glyph ID (which is not unicode neither ASCII value) correct widht is loaded. PDF file without patch: https://file.bukova.info/f/b4ce036838/?raw=1 PDF file with patch: https://file.bukova.info/f/a752893bce/?raw=1 It was to big for attachement so i have upload it to my server.
