I am using 2 datepickers on the same page with 2 languages(English, Japanese). The first time when I select the date in both date datepicker then it's working properly but second, the third time I select the date from Japanese and then I try to click & select date from English datepicker it shows Japanese characters for weekdays & month. It should show appropriate fonts for each language datepickers. Please help me to find out solution. Thanks in advance.
If you provide your code, we may be better able to help.
But according to the docs at https://api.jqueryui.com/datepicker/ you can specify the locale / language per picker in the setup parameters.
e.g.
$( selector ).datepicker( $.datepicker.regional[ "fr" ] );
