Export to pdf (Russian)

There is a problem when exporting words with Russian characters. How to solve?

Make sure you choose a unicode font in advanced setting of the dompdf extension.

Where and in what settings to do this? Please indicate the full path.
I looked at all the settings, I can not find where to choose unicode.

Read the topic Extensions > Using Extensions in the help file.

Extensions → dompdf → Advanced:
PdfBackend: TCPDF
PdfFront: DejaVuSansWhat needs to be changed here so that the Russian language is displayed correctly?

Make sure your project charset is set as utf-8 for unicode text support.

I need to display Russian and Chinese charactersAdvanced Settings:Character encoding (for Ajax/iconv) utf8
File system encoding utf8
MySQL charset (for SET NAMES) utf8orCharacter encoding (for Ajax/iconv) utf8mb4
File system encoding utf8mb4
MySQL charset (for SET NAMES) utf8mb4It not work. What else needs to be done?

For Chinese you need to use Chinese font (DejaVuSans does not support Chinese) with TCPDF. However, I doubt if the Chinese font supports Russian also, you need to test.

I tried all the options, nothing works. At least I need Russian.

id=3 - Russian
id=5 - Chinese

If you do not need both languages at the same time, first check the correct font for the different languages. From the notes of the dompdf extension:

  1. TCPDF - A free PDF engine and support unicode text. Change Charset to utf-8 for unicode text support.
    a. For CJK, use KozMinProRegular (Japanese Serif), KozGoProMedium (Japanese Sans-Serif), HYSMyeongJoStdMedium (Korean), or MSungStdLight (Trad. Chinese).
    b. For other non-English text, try to use the Free* or DejaVu* fonts.

After finding the correct fonts for the languages, modify the generated codes to switch to different font for the different languages.
