Support for non latin characters

[dubmassacre]

It would be nice if segrada could support data entry in non-latin characters for entities.

Whenever user types a non-latin character string, save fails and receives a message:

ERROR org.segrada.service.repository.orientdb.base.AbstractOrientDbRepository  - Exception thrown while saving entity.
com.google.common.util.concurrent.UncheckedExecutionException: java.lang.StringIndexOutOfBoundsException: String index out of range: 0

System configuration:
MacOS 10.14.6
Segrada 0.2.8

@dubmassacre : I cannot reproduce this behaviour any more in the current version? Do you still have this problem?

Tested 0.5.4 version on macos Catalina 10.15.7. Trying to create a new node with greek characters i get a 'SAVE FAILED' message and the following in terminal window.

Thanks for the hint. There was a bug in the old sluggify solution. I added a solution which will fix this issue. The update is scheduled for the next release (v0.5.5).
