Something that works great for ASCII +will choke for, e.g., en_US.UTF-8. One such program is test/gsubtst5.awk. + +By default, the test suite runs with LC_ALL=C and LANG=C. You +can change this by doing (from a Bourne-style shell): + + $ GAWKLOCALE=some_locale make check + +Then the test suite will set LC_ALL and LANG to the given locale. + +As of this writing, this works for en_US.UTF-8, and all tests +pass except gsubtst5. + +For the normal case of RS = "\n", the locale is largely irrelevant. +For other single byte record separators, using LC_ALL=C will give you +much better performance when reading records. Otherwise, gawk has to +make several function calls, *per input character* to find the record +terminator. You have been warned. |
