Checkpoint not working for multiple languages

[kafan1986]

I am training a single model supporting two languages.

For one of the languages, a row of training data looks like this:

&**ω⊃⊃&⟴∅ w i k k a t t i n u

The tensorboard during training phase gave correct entries but during inference phase using python pip package I am getting single character output for input. Using the same checkpoint the other language is working OK.
