1348 * A few notes about locales:
|
|
|
1349 *
|
|
|
1350 * (1) We don't use "case folding":
|
|
|
1351 * http://www.boost.org/doc/libs/1_64_0/libs/locale/doc/html/conversions.html
|
|
|
1352 *
|
|
|
1353 * Characters are made uppercase one by one. This is because, in
|
|
|
1354 * static builds, we are using iconv, which is visibly not
|
|
|
1355 * supported correctly (TODO: Understand why). Case folding seems
|
|
|
1356 * to be working correctly if using the default backend under
|
|
|
1357 * Linux (ICU or POSIX?). If one wishes to use case folding, one
|
|
|
1358 * would use:
|
|
|
1359 *
|
|
|
1360 * boost::locale::generator gen;
|
|
|
1361 * std::locale::global(gen(DEFAULT_LOCALE));
|
|
|
1362 * return boost::locale::to_upper(source);
|
|
|
1363 *
|
|
|
1364 * (2) The function "boost::algorithm::to_upper_copy" does not
|
|
|
1365 * make use of the "std::locale::global()". We therefore create a
|
|
|
1366 * global variable "globalLocale_".
|
|
|
1367 *
|
|
|
1368 * (3) The variant of "boost::algorithm::to_upper_copy()" that
|
|
|
1369 * uses std::string does not work properly. We need to apply it
|
|
|
1370 * one wide strings (std::wstring). This explains the two calls to
|
|
|
1371 * "utf_to_utf" in order to convert to/from std::wstring.
