App deletes note when &@ is in filename

[EthanYidong]

Steps to Reproduce

1. Create a file with &@ inside the name
2. Add the file
3. Close and relaunch the app

Expected

Nothing of note happens, app launches correctly

Actual

App states that save was corrupted and clears it

Severity

It may be unlikely that the user has notes with &@ in the name but it is not out of the question, and if they do they will be frustrated that they cannot add it in.

Their Response to the 'Original' Bug

[This is the team's response to the above 'original' bug]

This is the expected behavior. The use of &@ in the file name corrupts data file. Therefore when starting CLIAlgo it is treated as a corrupted entry and erased.

However we did not mention this in the UG therefore we accept this bug. However, we feel that the severity should be low because this flaw only affects files that contains &@ and the user can still use the application normally otherwise.
