Recognition doesn't run with Vietnamese lexicon

[ryanaleksander]

So I trained a model to detect and recognize Vietnamese text. However, if I load the model without using lexicon, it could only recognize English words. And if I load model with a Vietnamese lexicon file, the recognition task doesn't even run, the process is simply stuck after detection is finished.

This is my lexicon file: Viet74K.txt

Actually I found out that it just doesn't run when I switch default useLexicon in demo.lua to true no matter the lexicon file
