Prompt interrupted before continuation for Unicode UTF-8 emojis

[loretoparisi]

I have found that when having a Unicode UTF- emoji char like

Unicode Character “👍” (U+1F44D)

The prompts breaks up.

I'm reading a sample prompt from a text file:

cat prompt

Tweet: "I hate it when my phone battery dies."
Sentiment: Negative
###
Tweet: "My day has been 👍"
Sentiment: Positive
###
Tweet: "This is the link to the article"
Sentiment: Neutral
###
Tweet: "This new music video was incredibile"
Sentiment:

Looking at logs I can see in fact that the tokenizers breaks at the (U+1F44D) char code:

Twitter is not about talking; Twitter is a social network for listening and responding instantly, as the tweets of Steve Jobs demonstrate well in Figure A-2 (page ). Just be sure you can interpret the information accurately. If the sentiment isn't clearly positive or negative—as^C

resulting in a broken input prompt.

Its unable to support emojis without the unicode support fix. I have a branch or we can wait until more work is done here.
