The current code of the Belarussian currency is BYN according to ISO 4217 (https://www.currency-iso.org/en/home/tables/table-a1.html ) The current code in glibc has other value: (https://sourceware.org/git/?p=glibc.git;a=blob;f=localedata/locales/be_BY;h=defb2d782f0efa150eb5ac52e30bfaf13b1c9cb7;hb=HEAD#l105) LC_MONETARY int_curr_symbol "BYR " currency_symbol "<U0440><U0443><U0431>" mon_decimal_point "." mon_thousands_sep "<U202F>" mon_grouping 3;3 positive_sign "" negative_sign "-" int_frac_digits 2 frac_digits 2 p_cs_precedes 0 p_sep_by_space 1 n_cs_precedes 0 n_sep_by_space 1 p_sign_posn 1 n_sign_posn 1 END LC_MONETARY
It looks like Belarus underwent various currency reforms going from BYR to BYB to BYN. Do we have to adjust currency_symbol as well? Should it be "Br "?
In July 2016, a new ruble was introduced (ISO 4217 code BYN), at a rate of 1 BYN = 10,000 BYR. A Currency symbol is Br according Wikipedia (https://en.wikipedia.org/wiki/Belarusian_ruble)
