There are two things to consider when working with international languages: Typefaces A typeface that supports your character set must be installed on your server. These are normally automatically installed on modern web servers, but older servers may have been installed with older versions of some fonts such as Arial, which may not have full UTF-8 support. An alternative solution is to specify a Web Font in your CSS, such as those provided by Google Fonts. More information can be found in the article How to Use Google Fonts in Your Next Web Design Project. Input Encoding You may have to specify the input encoding of your document to render correctly. You may do this in the following ways: Adding an HTML "Meta Charset" Tag e.g. <meta http-equiv="Content-Type" content="text/html;charset=UTF-8"/> <meta http-equiv="Content-Type" content="text/html;charset=UTF-8"/> HTML Ready to see what else you can do? Check out our tutorial page here: Addtional Features Frequently Asked Questions How can I create a PDF with UTF-8 encoding in C#? To create a PDF with UTF-8 encoding in C#, use IronPDF's RenderHtmlAsPdf method. First, ensure that your HTML content includes UTF-8 encoded characters, then set the InputEncoding property to UTF8 before rendering. Why is UTF-8 important when generating PDFs? UTF-8 is crucial for PDF generation because it supports all Unicode characters, ensuring accurate rendering of international and special characters. IronPDF utilizes UTF-8 to comply with modern web standards, making it suitable for diverse language support. What are the typical challenges with UTF-8 PDF generation? Common challenges include ensuring proper character rendering for non-Latin scripts and managing fonts that support diverse character sets. IronPDF addresses these by allowing the use of web fonts like Google Fonts and setting the correct charset in the HTML. How do I render non-Latin scripts in a PDF using C#? To render non-Latin scripts in a PDF using C#, use IronPDF. Make sure your HTML content includes the necessary character set and specify a compatible web font if needed. IronPDF will handle the rendering of scripts like Chinese, Japanese, or Arabic. What steps should I follow to ensure correct UTF-8 encoding in my PDFs? To ensure correct UTF-8 encoding in PDFs, use IronPDF and include a meta charset="UTF-8" tag in your HTML. Set the ChromePdfRenderer.RenderingOptions.InputEncoding to UTF8 as well. How can I troubleshoot encoding issues in PDFs generated using C#? If you encounter encoding issues, check that your HTML includes a meta charset="UTF-8" tag and that you're using fonts that support your characters. IronPDF allows you to specify these settings to resolve encoding problems. Can I use Google Fonts to improve international language support in PDFs? Yes, Google Fonts can be used to improve international language support in PDFs. With IronPDF, you can specify these web fonts in your HTML, ensuring that all characters are displayed correctly in the generated PDF. What is the role of the 'Meta Charset' tag in PDF generation? The 'Meta Charset' tag defines the character encoding for your HTML content, which is crucial for rendering text correctly in PDFs. IronPDF uses this tag to ensure that UTF-8 encoded characters are processed accurately. Chaknith Bin Chat with engineering team now Software Engineer Chaknith works on IronXL and IronBarcode.
