============================
|
||
|
|
|
||
|
|
As noted in the NEWS file, as of 3.1.5, gawk uses character values instead
|
||
|
|
of byte values for `index', `length', `substr' and `match'. This works
|
||
|
|
in multibyte and unicode locales.

============================
|
||
|
|
|
||
|
|
Multibyte locales can cause occasional weirdness, in particular with
|
||
|
|
ranges inside brackets: /[....]/. 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.
