This is a default version of the tables that assumes ASCII encoding. A program
called dftables (which is distributed with PCRE2) can be used to build
alternative versions of this file. This is necessary if you are running in an
EBCDIC environment, or if you want to default to a different encoding, for
example ISO-8859-1. When dftables is run, it creates these tables in the
current locale. If PCRE2 is configured with --enable-rebuild-chartables, this
happens automatically.

/* Before version 10.32 the recursive calls of internal_dfa_match() were passed
local working space and output vectors that were created on the stack. This has
caused issues for some patterns, especially in small-stack environments such as
Windows. A new scheme is now in use which sets up a vector on the stack, but if
this is too small, heap memory is used, up to the heap_limit. The main
parameters are all numbers of ints because the workspace is a vector of ints.
The size of the starting stack vector, DFA_START_RWS_SIZE, is in bytes, and is
defined in pcre2_internal.h so as to be available to pcre2test when it is
finding the minimum heap requirement for a match. */

the stack can only grow in 4k steps. However, this function just burn
CPU cycles if the stack is large enough. However, you don't know it in
