We use next code to produce pdf file:

ByteArrayResource resource = new ByteArrayResource(outputStream.toByteArray(), "document.pdf");

headers.add(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=\"document.pdf\"");
return ResponseEntity.ok().headers(headers).contentType(MediaType.APPLICATION_OCTET_STREAM).body(resource);

}
@GetMapping("/testFonts")
public ResponseEntity<List<String>> getInstalledFonts() {

return ResponseEntity.status(HttpStatus.OK).body(availableFonts);
}
}
When we execute testPpdf route generated file doesn't contains Korean:
While we have installed Korean fonts, like Noto Sans KR, Noto Serif KR.
Attached source and API outputs.
