I walk through two under-the-radar updates in Tableau 2022.2: the upgrade to the ICU (International Components for Unicode) library and the QT framework library. I explain what each does and why you might notice changes in filtering, sorting, localisation and rendering, particularly for certain languages.

## Key takeaways

- The ICU library upgrade (from ICU44 to ICU68) governs how Unicode characters, alphabetical order and locale-specific sorting behave, so filters, sorts and ranges may shift in some languages.
- Chinese, Japanese and Korean (CJK) languages are most affected by the ICU change; English users are unlikely to notice much difference.
- Watch for inconsistencies in search, regex, locale formatting of numbers, times, currencies and temperatures, especially where logic relies on data persisted in a consistent sort order.
- The QT library is a third-party cross-platform framework Tableau uses to build its desktop interface across Linux, Windows and Mac; upgrading it can introduce rendering and UI defects.
- You can dig into the standards yourself at icu.unicode.org and qt.io, where Tableau is listed as a named QT customer.
