TCPDF do not display Chinese on Linux client

问题:

I cannot get TCPDF display any chinese character no matter what font I am using.

I crawled and searched everywhere I could, including these interesting posts

tcpdf-utf-8-problem
tcpdf-encode-chinese-character

but still without success.

The sample #7 from TCPDF works well with a lot of different characters sets but if I add some Chinese to the text it will display as squares and the strangest thing is if I change the font to stsongstdlight as suggested in one message the text won't display at all - but the header will.

The sample #38 from TCPDF with Japanese font doesn't work either. Thanks for any advice that could let me find new ideas to try.

I just tested setting the font like

$pdf->SetFont('kozminproregular', '', 12);

as suggested in tcpdf encode chinese character and it seemed to work fine.

Here is the sample from my output:

Main problem is due to evince PDF reader cannot handle the CJK Chinese generated by TCPDF. after

sudo apt-get install poppler-data

Everything started to get better ! I use the font stsongstdlight which is designed for Chinese unlike the kozminproregular which looks like designed for Japanese. However I have still an issue with the spacing of non Chinese character, there is very big spaces after all T,i,u...
To solve this second issue I convert and use the fonts arialuni.ttf but this font is not open source nor free. I tried to convert many other unicode fonts which include Chinese without success.
