International Components for Unicode (ICU) Date Formatter for MySQL? Regarding to ICU - International Components for Unicode definition:


  ICU is a mature, widely used set of C/C++ and Java libraries providing Unicode and Globalization support for software applications. ICU is widely portable and gives applications the same results on all platforms and between C/C++ and Java software.


one of important part is formatting:


  Formatting: Format numbers, dates, times and currency amounts according the conventions of a chosen locale. This includes translating month and day names into the selected language, choosing appropriate abbreviations, ordering fields correctly, etc. This data also comes from the Common Locale Data Repository.


which implemented in vary languages; I would like to know if there is any implementation or work for MySQL to add this feature for Unicode date formatting?
I think the answer is...  Use MySQL to store dates/datetimes/timestamps in the limited formats that it provides, then use app code -- possibly some library in your app language -- to get at fancier formatting.

As a general rule, a database is responsible for storing; the application is responsible for formatting.
