Turkish Characters: A Guide to Resolving Encoding Issues in CodeIgniter 3 and DomPDF

When working with Turkish characters in a CodeIgniter 3 project, you may encounter issues with encoding and displaying special characters. In this article, we will explore the challenges of displaying Turkish characters in DomPDF, a popular PDF generation library, and provide solutions to resolve these issues.

In your CodeIgniter 3 project, you are using DomPDF to print content from CKEditor 3, which was saved in the database. However, when displaying Turkish characters, you are experiencing trouble with characters such as ĞŞİ, ğş. You have defined the font-family as DejaVu Sans in the HTML generation for DomPDF, which has solved the issue for a good portion, but not completely.

The Role of Font Family

Font family plays a crucial role in displaying Turkish characters. In your case, you have defined the font-family as DejaVu Sans, which is a Unicode font that supports a wide range of languages, including Turkish. However, you have also tried defining the font as Times New Roman, which is a font that supports Turkish characters, but still failed to display the characters correctly.

Why Times New Roman Failed

Times New Roman is a font that supports Turkish characters, but it may not be the best choice for displaying Turkish characters in DomPDF. This is because Times New Roman is a font that is designed for printing, and it may not be optimized for displaying Turkish characters in a PDF document.

To resolve the issue of displaying Turkish characters in DomPDF, you can try the following solutions:

1. Use a Unicode Font

Use a Unicode font that supports Turkish characters, such as DejaVu Sans or Arial Unicode MS. These fonts are designed to display a wide range of languages, including Turkish.

2. Define the Font Family Correctly

Make sure to define the font family correctly in your HTML generation for DomPDF. Use the correct font name and family, and make sure to include the font file in your project.

3. Use the Correct Encoding

Use the correct encoding when saving the content in the database. Make sure to use a character encoding that supports Turkish characters, such as UTF-8.

4. Use a PDF Generation Library that Supports Turkish Characters

Consider using a PDF generation library that supports Turkish characters, such as TCPDF or Snappy. These libraries are designed to display Turkish characters correctly and may be a better choice for your project.

5. Use a Font that Supports Turkish Characters

Use a font that supports Turkish characters, such as Times New Roman or Arial. Make sure to define the font family correctly and include the font file in your project.

Displaying Turkish characters in DomPDF can be challenging, but there are solutions to resolve the issue. By using a Unicode font, defining the font family correctly, using the correct encoding, using a PDF generation library that supports Turkish characters, or using a font that supports Turkish characters, you can display Turkish characters correctly in your CodeIgniter 3 project.
