Modules for Backdrop CMS

I18n is a collection of modules to extend Backdrop core multilingual
capabilities and be able to build full-featured multilingual sites. This
module makes possible:

Helper module to prevent PDOExceptions, if your database isn't able to save
utf-8 4-byte characters, but users try to insert emojis, Asian symbols or
mathematical symbols.

If that happens, you get errors like:

International date formats and timezones are a mess. Let the browsers render
date fields in the right localized format and timezone and stop worrying
about that on your site.

This module provides support for displaying a date or time in the user's own time zone in both formatted date fields and (via token text) within the body of any formatted text field.

Luxon is a lightweight Backdrop module that provides the Luxon library (bundled with the module) for manipulating and formatting dates and times in Javascript.

@font-your-face provides an administrative interface for browsing and applying web fonts (using CSS @font-face, supported in all popular browsers) from a variety of sources.

This module will provide simple synchronization between Backdrop Nodes and
CiviCRM Groups based on rules defined by the administrator.

A module to refresh a view after a specified time interval.

Includes advanced options to avoid reloading the whole page, and to avoid
causing a full Backdrop bootstrap at each refresh.
