Error: Failed to convert locale string to UTF8

[lovebdsobuj]

Thanks for this very Useful Extension.
Generally this plugin works fine.

But after adding custom text in Bengali language, I got error When I click Datetime Format setting icon.

My Status bar datetime format string is:
আজ %A, %d %B %Y - %I:%M:%S %p

Error: Failed to convert locale string to UTF8: Invalid byte sequence in conversion input
