EntityText with especial character

[ran-j]

I want to do math with user input like:

Q : "how much is 2+2" R: "the answer is 4"

so I created a entity:

manager.addNamedEntityText('plus', 'plus', ['pt'], ['+','plus']);

And It does not recognizer my entity "+"

@ran-j I imagine this character is being filtered during nlp steps. If you are using v3 you can try setting "+" inside utteranceDict as 'plus'. In this way, this character will be replaced before starting the nlp process.

@ericzon Where would this be in v4?
