EncodeToIds takes a span but Encode takes a string. Is that ok? Are there places it'd be valuable for Encode to also take a span, or are there benefits to it being a string?

IIRC we chatted about that before. Encode need to return tokens, if we pass ReadOnlySpan here we'll need to call ToString on it again. EncodeToIds doesn't need return tokens and that is why we are ok to use spans there. I am open to any suggestion if we have a better ideas.

Hmm. Is that because we expect this text to frequently be a single token?

Tokenizers using Regex to pre-tokenize and produces a smaller or partial words is possible to be a single token. So it depends on the pre-tokenization and the vocabulary of the tokenizer. You had another idea which we decided not go with but we can reconsider it which is passing both string and span. This can help in the future if we expose Span apis on Tokenizer class.
