-------------------------
Version 10.35 15-April-2020
---------------------------
Bugfixes, tidies, and a few new enhancements.
1. Capturing groups that contain recursive backreferences to themselves are no
longer automatically atomic, because the restriction is no longer necessary
as a result of the 10.30 restructuring.
2. Several new options for pcre2_substitute().
3. When Unicode is supported and PCRE2_UCP is set without PCRE2_UTF, Unicode
character properties are used for upper/lower case computations on characters
whose code points are greater than 127.
4. The character tabless (for low-valued characters) can now more easily be
saved and restored in binary.
5. Updated to Unicode 13.0.0.

If you need to create alternative tables when cross compiling, you will have to
do so "by hand". There may also be other reasons for creating tables manually.
To cause <b>pcre2_dftables</b> to be built on the local host, run a normal
compiling command, and then run the program with the output file as its
compiling command, and then run the program with the output file as its
argument, for example:
<pre>
cc src/pcre2_dftables.c -o pcre2_dftables
./pcre2_dftables src/pcre2_chartables.c
./pcre2_dftables src/pcre2_chartables.c

This builds the tables in the default locale of the local host. If you want to
specify a locale, you must use the -L option:
<pre>
LC_ALL=fr_FR ./pcre2_dftables -L src/pcre2_chartables.c
</pre>
You can also specify -b (with or without -L). This causes the tables to be
written in binary instead of as source code. A set of binary tables can be
loaded into memory by an application and passed to <b>pcre2_compile()</b> in the
same way as tables created by calling <b>pcre2_maketables()</b>. The tables are
just a string of bytes, independent of hardware characteristics such as
endianness. This means they can be bundled with an application that runs in

If you need to create alternative tables when cross compiling, you will have to
do so "by hand". There may also be other reasons for creating tables manually.
To cause \fBpcre2_dftables\fP to be built on the local host, run a normal
compiling command, and then run the program with the output file as its
compiling command, and then run the program with the output file as its
argument, for example:

You can also specify -b (with or without -L). This causes the tables to be
written in binary instead of as source code. A set of binary tables can be
loaded into memory by an application and passed to \fBpcre2_compile()\fP in the
