 If the `small-icu` option is used, one can still provide additional locale data
 at runtime so that the JS methods would work for all ICU locales. Assuming the

 ICU is able to automatically find and load a variety of data formats, but the
 data must be appropriate for the ICU version, and the file correctly named.
