/*************************************************
*             PCRE2 testing program              *
*************************************************/

/* PCRE2 is a library of functions to support regular expressions whose syntax
and semantics are as close as possible to those of the Perl 5 language. In 2014
the API was completely revised and '2' was added to the name, because the old
API, which had lasted for 16 years, could not accommodate new requirements. At
the same time, this testing program was re-designed because its original
hacked-up (non-) design had also run out of steam.

/* This program supports testing of the 8-bit, 16-bit, and 32-bit PCRE2
libraries in a single program, though its input and output are always 8-bit.
It is different from modules such as pcre2_compile.c in the library itself,
which are compiled separately for each code unit width. If two widths are
enabled, for example, pcre2_compile.c is compiled twice. In contrast,
pcre2test.c is compiled only once, and linked with all the enabled libraries.
Therefore, it must not make use of any of the macros from pcre2.h or
pcre2_internal.h that depend on PCRE2_CODE_UNIT_WIDTH. It does, however, make
use of SUPPORT_PCRE2_8, SUPPORT_PCRE2_16, and SUPPORT_PCRE2_32, to ensure that
it references only the enabled library functions. */

the original UTF-8 definition of RFC 2279, which allows for up to 6 bytes, and

limit of 0x10ffff cause an error. In non-UTF mode the input is interpreted as
UTF-8 if the utf8_input modifier is set, but an error is generated for values
greater than 0xffff.

If all the input bytes are ASCII, the space needed for a 16-bit string is
exactly double the 8-bit size. Otherwise, the size needed for a 16-bit string
is no more than double, because up to 0xffff uses no more than 3 bytes in UTF-8

In non-UTF mode the input is interpreted as UTF-8 if the utf8_input modifier
is set, and no limit is imposed. There is special interpretation of the 0xff
byte (which is illegal in UTF-8) in this case: it causes the top bit of the
next character to be set. This provides a way of generating 32-bit characters

If all the input bytes are ASCII, the space needed for a 32-bit string is
exactly four times the 8-bit size. Otherwise, the size needed for a 32-bit
