# Bug Tracker

ID: 125 🔗 Closed (Not a Bug) datatool v2.27 ThreePhaseEel 2017-10-07 18:00:41 datatool + utf8 special chars in raw CSV import = sounds of breaking LaTeX

## Report

MWE (test.tex, MUST HAVE TEST.CSV TO WORK):
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{datatool}
\begin{document}
\tableofcontents
\appendix
\section{Bill of Materials}

\DTLdisplaydb{bom}
\end{document}

MWE (test.csv) (was UTF-8 encoded until the mojibake happened, can send separately if needed, LMK if you want a separate report about your bug report form):
"name","quantity"
"10μF 16V",5
"470Ω 1/2W",10
"33k×9",1

Salient error:
! Undefined control sequence.
\GenericError  ...
#4  \errhelp \@err@     ...

Full logs:

(See [How do I get datatool to play nicely with utf8 inputenc and non-ASCII in the incoming CSV?] for more details and a non-mojibake'd test.csv btw)

### MWE

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{datatool}
\begin{document}
\tableofcontents
\appendix
\section{Bill of Materials}

\DTLdisplaydb{bom}
\end{document}


## Evaluation

(I removed the log from your message as it's too noisy. The bug report script has saved the accompanying log file.) It's not a bug as you also get an error with just:
\documentclass{article}
\usepackage[utf8]{inputenc}
\begin{document}
10μF 16V, 5
470Ω 1/2W, 10
33k×9, 1
\end{document}

and your MWE works fine with recognised UTF-8 characters. For example, if test.csv is changed to:
"name","quantity"
"éîà",1

You need to map the unrecognised UTF-8 characters (as in Alan Munn's answer) or use a UTF-8 aware engine.
