Sometimes we use characters in messages sent via Groupcall Messenger that are used less often e.g. the £ character, or a ¬ or sometimes 'fancy' quotation marks, as well as many characters used in foreign languages. In these cases, in order for the message to display correctly when they are received, we need to send them using a different system, this system is called Unicode. This is great, but it does mean that each of the characters now takes twice the space that it did previously (even the regular characters!).
