glibc doesn't work

[rfmuniz]

i set locale to pt_BR:

I am using docker file, and set this variables:

ENV LD_LIBRARY_PATH /usr/glibc-compat/lib
RUN /usr/glibc-compat/bin/localedef -i pt_BR -f UTF-8 pt_BR.UTF-8
ENV LANG pt_BR.UTF-8
ENV LANGUAGE pt_BR.UTF-8
ENV LC_ALL pt_BR.UTF-8

my locale -a:

/usr/glibc-compat/bin/locale -a

C POSIX pt_BR.utf8

Ex: My locale monetary /# /usr/glibc-compat/bin/locale -k LC_MONETARY int_curr_symbol="BRL " currency_symbol="R$" mon_decimal_point="," mon_thousands_sep="." mon_grouping=3;3 positive_sign="" negative_sign="-" int_frac_digits=2 frac_digits=2 p_cs_precedes=1 p_sep_by_space=1 n_cs_precedes=1 n_sep_by_space=1 p_sign_posn=1 n_sign_posn=1 crncystr="-R$" int_p_cs_precedes=1 int_p_sep_by_space=1 int_n_cs_precedes=1 int_n_sep_by_space=1 int_p_sign_posn=1 int_n_sign_posn=1 duo_int_curr_symbol="BRL " duo_currency_symbol="R$" duo_int_frac_digits=2 duo_frac_digits=2 duo_p_cs_precedes=1 duo_p_sep_by_space=1 duo_n_cs_precedes=1 duo_n_sep_by_space=1 duo_int_p_cs_precedes=1 duo_int_p_sep_by_space=1 duo_int_n_cs_precedes=1 duo_int_n_sep_by_space=1 duo_p_sign_posn=1 duo_n_sign_posn=1 duo_int_p_sign_posn=1 duo_int_n_sign_posn=1 uno_valid_from=10101 uno_valid_to=99991231 duo_valid_from=10101 duo_valid_to=99991231 conversion_rate=1;1 monetary-decimal-point-wc=44 monetary-thousands-sep-wc=46 monetary-codeset="UTF-8" / #

But in python, my locale don't get this config:

>>> import locale
>>> 
>>> locale.localeconv()['frac_digits'] 
127
>>> locale.localeconv()['currency_symbol']
''

How I set the frac_digits to 2, in python ? or currency_symbol to R$ ?
