Many of the fmt_*() functions have a locale argument that makes
locale-based formatting easier. The table generated by the info_locales()
function provides a quick reference to all the available locales. The locale
identifiers are provided (base locale ID, common display name) along with the
each locale's group and decimal separator marks. A formatted numeric example
is provided (based on the value of 11027) to demonstrate the default
formatting of each locale.
info_locales(begins_with = NULL)An object of class gt_tbl.
Providing a single letter will filter locales to only
those that begin with that letter in their base locale ID. The default
(NULL) will produce a table with all locales displayed.
Get a table of info on all of the locales where the base locale ID begins
with a "v".
info_locales(begins_with = "v")

10-4
There are 712 locales, which means that a very long display table is provided
by default. To trim down the output table size, we can provide an initial
letter corresponding to the base locale ID to begins_with. This will filter
locales in the info table to just the set that begins with the supplied
letter.
