About sentencepiece
The R binding to Google's tokenizer has shipped nothing but compiler fixes since 2021.
sentencepiece wraps Google's subword tokenizer for R, exposing BPE and unigram encoding, model training and the BPEembed interface. Functionally it has been frozen since 0.2, which upgraded the vendored library to sentencepiece v0.1.96 and fixed a wordpiece bug for one-character words. Every release since is toolchain work: UBSAN, snprintf on M1 Macs, dropping C++11, then requiring C++17.
