Portrait change text command doesn't work if there are any '/' characters in the portrait name

[klein-eng]

The problem

Describe the bug
I would expect the following portrait change command to work:
John (CloseUp/Happy): "My expression changes [portrait=CloseUp/Sad] while speaking."
However, what actually ends up being output is:
"My expression changes CloseUp while speaking." or "My expression changes Sad while speaking."

It seems like the [option1/option2] random choice command is interfering with the portrait command when there are any '/' characters in the portrait name. Because the '/' character is used for portrait groupings, this would come up fairly often.

Expected behavior
Even if there is a '/' character in the portrait name, the example above would change John to the CloseUp/Sad portrait.

System (please complete the following information):

• Godot Version: 4.1
• Dialogic Version: 2.0
