CODE128: error on unrecognized extra escape sequences instead of
just passing them thru;
fix possible shifting before manual FNC1 in 2nd position
after single alpha (otherwise won't be recognized as AIM)
fix not removing manual FNC1 in 1st/2nd position from content
segs (as implied by symbology identifier)
CLI: warn if both "--dmre" and "--square" given (as "--square"
overwrites "--dmre")
common: new routines `z_isalpha()`, `z_extra_escapes()` and
`z_ct_set_seg_extra_escapes_eci()`
library: new helper `supports_extra_escape_mode()`;
fix some error_number dups
BWIPP: update to latest, and allow for removal of DBAR_LTD_CC RHS
quiet zones & extra row when have add-on in EAN/UPC composites
test suite: fix BWIPP escaping
manual/man/tcl: update for DATAMATRIX manual FNC1 support
Windows: resource scripts: make more consistent (libzint, CLI, GUI)
win32/README: update with MSVC 2026
`options_3`, allowing forcing of Base 256 or C40 mode a la BWIPP
for initial no. of characters specified in `option_1`, with 0
meaning all (CLI "--dmb256=" and "--dmc40=", GUI also (apart
from MAILMARK_2D, which may be added later);
export masks `DM_B256_C40_START_MASK` & `DM_SQUARE_DMRE_MASK` in
"zint.h"
ZBarcode_Encode_File: report filename (possibly truncated) in error
message on failed open
GUI: uniquify some accelerators and add some child widget getter
helpers to "mainwindow.cpp"
backend/DEVELOPER -> backend/README, with some expansion
debian/copyright: a few more fixes
BWIPP/pandoc: update to latest
tests/fuzz: adjust for new DATAMATRIX options
Add FAST_MODE input_mode flag and --fast CLI/Tcl option that selects older
faster ISO algorithm (may be used by other symbologies in the future)
and "Fast Encoding" checkbox to Data Matrix GUI
GUI: adds Zint version numbers to DATAMATRIX sizes.
GRIDMATRIX, MAXICODE, MICROPDF417, PDF417, QRCODE, ULTRA
DOTCODE: use pre-calculated generator poly coeffs in Reed-Solomon for
performance improvement
PDF417/MICROPDF417: use common routine pdf417_initial()
GUI: code lines <= 118, shorthand widget_obj(),
shorten calling upcean_addon_gap(), upcean_guard_descent()
various backend: var name debug -> debug_print
