• UTF-8 support – PDLS 10.0.0 now fully supports UTF-8 encoded text across all modules, enabling developers to render international text in multiple languages in a single application.
• 16-bit multilingual font engine – The font subsystem has been upgraded from 8-bit to 16-bit wide glyph indices, significantly expanding the number of characters that can be included. This opens new applications requiring non-Latin character sets like Chinese, Japanese, Arabic, Hebrew as shown above.
• Backward compatibility and migration path – The new version retains the previous API for text and graphics primitives, and advanced graphics and GUI controls, while adding the new font features. The technical note Migrate from release 9 to release 10 provides a transition path to existing applications built on prior releases.
• Improved performance and memory usage – Under the hood, version 10.0.0 brings optimizations for font caching, reducing the memory footprint up to 33% compared to previous release. A technical note explains how to optimize the size of the 16-bit fonts.
• Enhanced documentation and sample projects – The Knowledge Base, the User Guide and the Reference Manual have been updated and include examples for multilingual rendering and GUI construction with the new features.
