Localization of DatePicker

Localization of DatePicker


When the .regional setting is made (e.g. .regional['fr']), am I
correct in thinking that the corresponding "fr" file (ui.datepicker-
fr.js) is accessed and the settings from that file (closeText,
prevText, datName, etc) are applied?
My reason for asking is that in my application, I am using zh-CHS as
simplified Chinese - the name of the corresponding file contains "zh-
CN".
If I were to rename the ui.datepicker-zh-CN.js to ui.datepicker-zh-
CHS.js would I get the correct localization settings?
Thanks
