Description

I am a longtime user of the DATATOOL package. It is a GREAT package. Many thanks for providing this!

It looks like the new DATATOOL version has a problem if the INPUTENC package is loaded with latin1 support.

The LaTeX error message is as follows:

File: datatool-latin1.ldf 2025/12/04 v3.4.3 (NLCT)

! Undefined control sequence.
l.44 \datatool_set_currencysign_from_charcode:ne

There is the following MWE.
Please note that INPUTENC with latin1 option is loaded before DATATOOL, not after.

\documentclass{article}
\usepackage[latin1]{inputenc}
\usepackage{datatool}

\begin{document}
Datatool.
\end{document}

This problem has been earlier by somebody else on stack-exchange, but without solution, only workarounds: [TeX.SX Link]

Workarounds are:
- load DATATOOL before loading INPUTENC
- use UTF8 instead of Latin1 encoding
Neither of these workarounds is suitable for me. For certain reasons I have to stick with Latin1.

So far I was using DATATOOL 2019/09/27 v2.32 in all my LaTeX documents (many hundreds) without problems. I would love to migrate to the new 3.xx generation but this problem with `\datatool_set_currencysign_from_charcode` hinders me to do that. I am not using any currently features with DATATOOL.

I would really appreciate a solution or any other workaround so that I can start working with the new DATATOOL version.
Thanks

Evaluation

I've corrected the error and uploaded v3.4.4 to CTAN. Please allow a few days for it to reach your TeX distribution.
