Any suggestion for a temporary fix?

Here is very dirty workaround / backup all file before doing these steps. ->

1. Get Thai font and upload to /lib/web/fonts (Font-version must be table v3, since the library can't parse table v4 font.)
2. Change font-location to uploaded fonts' location in /vendor/magento/module-sales/Model/Order/Pdf/AbstractPdf.php

   function _setFontRegular
   function _setFontBold
   function _setFontItalic

** you might need to adjust font size according to your font, finding "setFontSize"

1. Modify $drawingString in same file :: /vendor/magento/module-sales/Model/Order/Pdf/AbstractPdf.php

        $drawingString = '"libiconv"' == ICONV_IMPL ? iconv(
            'UTF-8',
            'UTF-16BE//IGNORE',
            $string
        ) : @iconv(
            'UTF-8',
            'UTF-16BE',
            $string
        );

to

        $drawingString = mb_convert_encoding($string, "UTF-16BE", "UTF-8");

If you get the error about cannot convert MacRoman. then you might have to edit /vendor/magento/zendframework1/library/Zend/Pdf/FileParser.php and look for

function readStringMacRoman

replace

return iconv('MacRoman', $characterSet, $bytes);

with

return mb_convert_encoding($bytes, $characterSet, 'UTF-8');

PS. This is not appropriate way to deal with this issue. However LinLibertineFont contains no Thai-characters , and iconv lib can't properly convert MacRoman to UTF16BE (Used in thai font like TH Sarabun)

PS.2. This is very dirty fix. If your store is in EN/TH then it might work. But this might raise some errors if dealing with other char-encoding.

-------- BTW, Thai-font issue is in magento since 1.xx

Hello,
https://github.com/magento/magento2/commit/abd7be087cebeae8109f8d998d24361cedb2d554

this fix is not enough to fix the problem. the characters become supported but. still the letters are not connected together.

[o0mohammed0o]

After long investigation I found that zend pdf library doesn't support arabic language.
the solution for this is to use extension use another pdf library.
i found this extension uses another library and support arabic. you have to pay for it sorry didn't found free one. https://www.vnecoms.com/magento2-extensions/magento2-pdf-invoice-pro.html
