6. Conclusion

The Adobe Illustrator CC 17.1 (171) Final Multilingual Update was a net positive for global users, reducing language-related crashes and improving text rendering. However, it inadvertently harmed automation workflows reliant on legacy ASCII assumptions. Users requiring heavy scripting should remain on 17.0 or rewrite scripts using Unicode-safe methods. This update marks a turning point where Adobe prioritized human usability over machine automation—a philosophical shift that continues to shape the software today. Draw closed paths with smoother curves

• Draw closed paths with smoother curves.
• Adjust fidelity and smoothness in real time.
• Edit existing paths by drawing over them (similar to Freeform editing).

• Time to first glyph render (ms).
• Crash rate per 100 language switches.
• Script failure rate (error code -2147467259 vs. success).
• Memory footprint after loading 5 multilingual files.

5.2 Critical Regression: Scripting
Adobe changed the internal string encoding for layer and swatch names from MacRoman/Windows-1252 to UTF-16LE without updating the ExtendScript DOM. Scripts comparing strings using == failed because byte-order marks (BOM) differed. Recommendation: Use localCompare() or convert to UTF-8 before comparison. Time to first glyph render (ms)
