Special characters encoding

[itafraze]

Possibly related to #324, special characters handling can be improved. Consider the following element:

It is being stored in Postgres as (once untangling the json-formatted string):

 level |       parent_name       |      parent_class      |       child_name        |      child_class       |                               child_body                               |                                                                                                                                                                                                          child_body_ascii

As long as the objects are cached, the visualisation is correct. However, once SysON is restarted and the database content loaded, the result is:

This behaviour could be inherited from https://github.com/eclipse-sirius/sirius-web but I have not tested it.

Hello,
Thank you for reporting this problem.
I didn't succeed in reproducing the problem with my local install of SysON (on macOS).
Anyway, It can be fixed in SysON directly. For this part, we rely on Sirius Web, (as you mentioned it) a framework to easily create and deploy graphical studios to the web.
I will raised an issue on Sirius Web github repository.
Regards,
