having problems with greek characters in a table using csvsimple

Question

Hi this is what I wrote:

\documentclass{article}
\usepackage{amsmath}
\usepackage{gensymb}
\usepackage[utf8]{inputenc}
\usepackage{csvsimple}
\usepackage{booktabs}
\usepackage{longtable}
\usepackage[T1]{fontenc}

\begin{document}
\csvautotabular{Book2.csv}

\end{document}

and this is the content of the csv file, i made it with excel and converted with notepad++

frequenza ν (Hz),frequenza teorica ν (Hz) ,nodi n
510,537.18,2
760,805.78,3
1010,1074.38,4
1280,1342.97,5
1550,1611.56,6

It fails creating the PDF, this is the error message:

Package gensymb Warning: Not defining \perthousand.
Package gensymb Warning: Not defining \micro.

! Undefined control sequence.
\GenericError  ...                                
                                                    #4  \errhelp \@err@     ...
l.12 \csvautotabular{Book2.csv}

? ^C! Interruption.
\GenericError  ...                              #4
                                                    \errhelp \@err@         ...
l.12 \csvautotabular{Book2.csv}

Thank you for your answers

A possible solution is to compile with xelatex and polyglossia, see https://tex.stackexchange.com/a/329750/ for an example. — Marijn, Aug 29 '19 at 17:02
Thank you, it now creates the pdf with the table, sadly the greek character isn't displayed — user195519, Aug 29 '19 at 17:25

For pdflatex you can map the ν character in the input to $\nu$ using \newunicodecharacter. However, csvsimple does not allow macros in header lines because the header values are used to create keys to refer to the corresponding columns. A workaround for that is to disable the code that creates the keys.

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{csvsimple}
\usepackage{newunicodechar}
% map ν in input to macro
\newunicodechar{ν}{$\nu$}

\makeatletter
% switch off csvsimple column name macros
\def\set@csv@head{\relax}
\makeatother

\begin{document}
\csvautotabular{book2.csv}

\end{document}

Result:

If you don't want to define the character mapping yourself then you can use the alphabeta package - note however that the characters look a bit different.

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{csvsimple}
\usepackage{alphabeta}

\makeatletter
% switch off csvsimple column name macros
\def\set@csv@head{\relax}
\makeatother

\begin{document}
\csvautotabular{book2.csv}

\end{document}

Probably a font problem; with Gentium and xelatex seems to work:

\documentclass{article}
\usepackage{fontspec}
\usepackage[greek, italian, english]{babel}
\setmainfont[Mapping=tex-text]{Gentium}
\usepackage{amsmath}
\usepackage{csvsimple}

\begin{document}
\csvautotabular{Book2.csv}
\end{document}
