UnicodeEncodeError about nomic HOT 1 CLOSED

Trying to construct a text map using atlas, it can work when I sample a small number of data. But when I use all the data, it got errors:

UnicodeEncodeError: 'utf-8' codec can't encode characters in position 2350-2351: surrogates not allowed

I have removed all the non-ASCII data but still got the error, any ideas?

FIxed. There still are some weird characters..
