Increase the character limit of the MAILTO function

The MAILTO function currently has a limit of around 2000 characters and any greater than this will prevent the message from being opened in your chosen mail app.

 

This is normally fine for standard English alphabetic characters, but can cause issues for non-English alphabetic characters. For example the Japanese character キ get converted to %E3%82%AD. This means the character limit gets reached very quickly for a message in Japanese. 

 

I would like the character limit of the MAILTO function to be increased. This would remove potential restrictions on non-English languages.
