программа для тестирования регулярных выражений, совместимых с Perl (a program for testing Perl-compatible regular expressions.)
PCRE's 8-BIT, 16-BIT AND 32-BIT LIBRARIES
From release 8.30, two separate PCRE libraries can be built. The
original one supports 8-bit character strings, whereas the newer
16-bit library supports character strings encoded in 16-bit
units. From release 8.32, a third library can be built,
supporting character strings encoded in 32-bit units. The
pcretest program can be used to test all three libraries.
However, it is itself still an 8-bit program, reading 8-bit input
and writing 8-bit output. When testing the 16-bit or 32-bit
library, the patterns and data strings are converted to 16- or
32-bit format before being passed to the PCRE library functions.
Results are converted to 8-bit for output.
References to functions and structures of the form pcre[16|32]_xx
below mean "pcre_xx when using the 8-bit library, pcre16_xx when
using the 16-bit library, or pcre32_xx when using the 32-bit
library".
