Ah, ok. If ripgrep can do this as well, it would be more general (a good 
thing).

Note that it mentions the following in the description of its -b argument:

  If ripgrep does transcoding, then the byte offset is in terms of the
  the result of transcoding and not the original data. This applies
  similarly to another transformation on the source,
  such as decompression or a --pre filter. Note that when the PCRE2
  regex engine is used, then UTF-8 transcoding is done by default.
