Multi-lingual support for HTML to PDF (wkhtmltopdf / Headless Chrome)
Intro – HTML to PDF with Multiple Languages
A frequent question we receive at API2PDF is if it is possible to generate PDFs with foreign languages, or languages that contain special characters in their text. The answer is yes, and it is possible to support these languages in both wkhtmltopdf and Headless Chrome rendering engines.
Include Special Language Characters in PDFs
We support most of what is supported by unicode characters, or UTF-8. The trick is to include <meta charset=”UTF-8″> in the <head> section of your HTML. If you do this, unicode characters should properly appear. We ran a test by copying and pasting the HTML below into the Try It Out section on the home page of api2pdf.com which uses Headless Chrome.
