Resolving Cyrillic Value Export Issue in Jasper Reports PDFs

When exporting Jasper reports as PDFs, Cyrillic values often fail to display. While these values are correctly rendered in XLS format, the PDF export process encounters difficulties with Cyrillic characters. This article explores the reasons behind this issue and provides solutions to resolve it.

The issue pertains to compatibility with the iText library utilized by Jasper Reports for PDF generation. To ensure successful Cyrillic character rendering, a series of factors must be considered.

1. Font Support:

• Verify that the font used in the report supports OpenType and is capable of rendering Cyrillic characters. Not all fonts possess this capability.

2. Encoding:

• Utilize Identity-H encoding. This encoding is widely supported and enables the mixing of different character sets.

3. Font Embedding:

• Embed fonts in the PDF to ensure proper display even on computers that do not possess the necessary font.

4. Deprecated Method vs. Non-Deprecated Method:

• Set attributes on the textElement using the non-deprecated method in Jasper Reports versions 3-6. This involves adding Font Extensions and generating a JAR for the font extension using tools like iReport or JasperSoft Studio.

Conclusion:

By addressing the factors described in this article, users can resolve the issue of Cyrillic value export in Jasper Reports PDFs. Ensuring proper font support, encoding, font embedding, and using the non-deprecated method will result in successful PDF exports with accurate Cyrillic character display.
