This patch integrates Wikimedia's jQuery.IME multi-lingual input method
jQuery based library with Koha, for the OPAC as well as the staff
client.

Terms of Service (ToS) are not FOSS friendly. In contrast, jQuery.IME
is dual-licensed under GPLv2+ and MIT. It is a key component of
Wikimedia's global language engineering stack. At present, this
represents robust, well tested support for over 135 input methods
spanning over 67 languages.
