encodation in certain cases (and no pessimizations found so far), props lyngklip (BWIPP); fix extended char latching when exactly 3 extended chars at end; count code set C (not digits) in loop deciding when to shift/latch to extended for better estimate AZTEC: return warning if ECC < 5% (due to bit-stuffing when version given); return error if > 22 layers (Zint 26) for Reader Initialisation symbol requested for better error message AZTEC/HANXIN/QRCODE: consolidate different ECC data size tables into one indexed by ECC DBAR_EXP: check for reduced length <= 77 up front for better error message HANXIN: use `malloc()` rather than `z_alloca()` for large binary array QRCODE: `ecc_level` now 0-based (not 1-based) MICROQR: consolidate different version end routines into one `microqr_end()` and use new `microqr_data` table to simplify code MICROPDF417: use table for max codewords per column library: centralize all error messages using new `errtxt()`, `errtxtf()`, `errtxt_adj()` funcs that protect `symbol->errtxt` from overflow, & try to make error messages more consistent thru-out, adding more feedback info to many, & use positional args "%n$" in prep for l10n (maybe); `is_sane/is_sane_lookup()` -> `not_sane/not_sane_lookup()`, returning 1-based position (zero on failure) instead of bool; `long` ints -> plain `int` (except those dealing with `ftell()`, `fread()` etc) as depend on int being 32-bits already GUI: in "grpDATF.ui" use "PlainText" rather than "RichText" for tracker ratio examples as height of text messing up sometimes manual: clarify Codablock-F length maximum & add examples docs: README: pandoc 3.5, Ubuntu 24.04 CMake: use "-Wpedantic" for Clang only as GNU complains about `errtxtf()` positional args "%n$" |

Zint and libzint
----------------
Zint is a suite of programs to allow easy encoding of data in any of the
wide range of public domain barcode standards and to allow integration of
this capability into your own programs.

Australia Post Reply-Paid GS1 DataBar Expanded Stacked
Australia Post Routing Code GS1 DataBar Limited
Australia Post Standard Customer GS1 DataBar Omnidirectional
Aztec Code (and HIBC) GS1 DataBar Stacked
Aztec Runes GS1 DataBar Stacked Omnidirectional
BC412 (SEMI T1-95) Han Xin (Chinese Sensible) Code
Brazilian Postal Code (CEPNet) ISBN
Channel Code ITF-14
Codabar Japanese Postal Barcode
Codablock-F (and HIBC) Korean Postal Barcode
Code 11 LOGMARS
Code 128 (and GS1-128 and HIBC) MaxiCode
Code 16K MicroPDF417 (and HIBC)

BEFORE POSTING TO THE LIST
--------------------------
Please note the following points...
* Zint is primarily developed for Linux. While we have some experience of
using Zint on Windows we may be unable to resolve problems if they are
specific to other operating systems. We cannot provide support for using
Zint with commercial packages such as MS Office or Crystal Reports.
* Always ensure you are using the latest version of Zint before posting bug
reports - the bug you are reporting may have been fixed already.
* Please remember to state what operating system you are using and include
enough information to allow us to reproduce the error - including input
data if appropriate.
* Please DO NOT post messages asking for us to change the license
arrangements. You will be ignored.
* Please remember that Zint is developed by volunteers. While we attempt to
answer all messages within a week, this is highly dependent on external
circumstances.
