201 ISO/IEC 9899:2018 (ISO C17), and POSIX.1-2017. Within 30112 we have the
202 definition of a standard i18n FDCC-set, which for LC_MONETARY has the
203 following default values:
204 int_curr_symbol ""
205 currency_symbol ""
206 mon_decimal_point "<U002C>" i.e. ","
207 mon_thousand_sep ""
208 mon_grouping "\177" i.e. CHAR_MAX
209 positive_sign ""
210 negative_sign "<U002E>" i.e. "."
211 int_frac_digits -1
212 frac_digits -1
213 p_cs_precedes -1
214 p_sep_by_space -1
215 n_cs_precedes -1
216 n_sep_by_space -1
217 p_sign_posn -1
218 n_sign_posn -1
219 Under 30112 a keyword that is not provided implies an empty string ""
220 for string values or a -1 for integer values, and indicates the value
221 is unspecified with no default implied. No errors are considered.
222 The exception is mon_grouping which is a string with a terminating
223 CHAR_MAX.
224 For POSIX Issue 7 we have:
225 https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap07.html
226 and again values not provided default to "" or -1, and indicate the value
227 is not available to the locale. The exception is mon_grouping which is
228 a string with a terminating CHAR_MAX. For the POSIX locale the values of
229 LC_MONETARY should be:
230 int_curr_symbol ""
231 currency_symbol ""
232 mon_decimal_point ""
233 mon_thousands_sep ""
234 mon_grouping "\177" i.e. CHAR_MAX
235 positive_sign ""
236 negative_sign ""
237 int_frac_digits -1
238 frac_digits -1
239 p_cs_precedes -1
240 p_sep_by_space -1
241 n_cs_precedes -1
242 n_sep_by_space -1
243 p_sign_posn -1
244 n_sign_posn -1
245 int_p_cs_precedes -1
246 int_p_sep_by_space -1
247 int_n_cs_precedes -1
248 int_n_sep_by_space -1
249 int_p_sign_posn -1
250 int_n_sign_posn -1
251 Like with 30112, POSIX also considers no error if the keywords are
252 missing, only that if the cateory as a whole is missing the referencing
253 of the category results in unspecified behaviour.
254 For ISO C17 there is no default value provided, but the localeconv
255 specification in 7.11.2.1 admits that members of char * type may point
256 to "" to indicate a value is not available or is of length zero.
257 The exception is decimal_point (not mon_decimal_point) which must be a
258 defined non-empty string. The values of char, which are generally
259 mapped to integer values in 30112 and POSIX, must be non-negative
260 numbers that map to CHAR_MAX when a value is not available in the
261 locale.
262 In ISO C17 for the "C" locale all values are empty strings "", or
263 CHAR_MAX, with the exception of decimal_point which is "." (defined
264 in LC_NUMERIC). ISO C17 makes no exception for mon_grouping like
265 30112 and POSIX, but a value of "" is functionally equivalent to
266 "\177" since neither defines a grouping (though the latter terminates
267 the grouping).
268
269 Lastly, we must consider the legacy C/POSIX locale that implemented
270 as a builtin in glibc and wether a default value mapping to the
271 C/POSIX locale may benefit the user from a compatibility perspective.
272
273 Thus given 30112, POSIX, ISO C, and the builtin C/POSIX locale we
274 need to pick appropriate defaults below. */

283 earlier when a default category is created (completely missing category).
