Feature request: Unicode characters as places instead of circles

[mattgig]

At the moment every place on the the map is a circle of a certain colour. I suggest adding the possibility to replace this circle by an optional unicode character. This would also help to solve #52.

Why the additional functionality?

Example 1: In a language course their might be different acitivities like:

• vocabulary learning
• grammar exercises
• listening / reading comprehension
• writing and speaking tasks
• ...

Example 2:
In a math course a teacher might like to differentiate tasks depening on how difficult there are to solve. Different symbols can help to make the students aware (of the danger) awaiting them.

Using such an approach, teachers and students would get a visual representation of the type of journey ahead of them. Especially when a course makes use of optional activities and allows for different paths to a certain destination.

Things to consider

Changing the code to display a unicode character instead of a circle will probably be trivial. However, to be able to choose an individual character for each place the user interface needs to be changed. In addition, in the database, you will have to add an additional field to store the unicode character for each place.
Furthermore, the ability to add unicode characters will probably lead to an additional feature request, asking for the possibility to use different fonts with the learning map.
