[Orgmode] [babel] Sh problem when echo'ing input data with ' inside

[Sébastien Vauban]

Hi,

I tried to work on a CSV2Ledger, accepting the particular (European) CSV
format of my bank:

* Data

#+results: excel-from-bank
#+begin_example
Numéro du compte :;979-9500975-24;Compte Maxi
Date valeur;Référence de l'opération;Description;Montant de 
l'opération;Devise;Date d'opération;Compte de contrepartie;Nom de la 
contrepartie :;Communication 1 :;Communication 2 :
04-06-2009;A9F04NT01WK300TG;Virem. 
internet;420,00;EUR;04-06-2009;799-5900947-23;PAYEE ONE; ; 
24-02-2009;A9B24NT012K4018Z;Virem. 
internet;-54,93;EUR;24-02-2009;799-9974005-30;ME;Eigen rekening; 
18-05-2008;A8E19NT000S604QI;Virem. 
internet;-1.000,00;EUR;19-05-2008;799-8068445-18;PAYEE TWO; ; 
#+end_example

* "Europeanize" the CSV file

Here, we have to make several manipulations on the input file, such as:
- remove dots from amounts
- replace commas from amounts by dots
- replace semi-commas by commas
- etc.

My goal is to make that as a suite of bash commands (=echo | cmd 1 | cmd 2=),
tangled in a script file.

However, I can't do any work on the input file, the very basic echo command
already giving an error:

#+begin_src sh :var data=excel-from-bank :results output
echo "$data"
#+end_src

#+results:
Code block produced no output.

#+begin_src stderr
sh: line 3: unexpected EOF while looking for matching `''
sh: line 10: syntax error: unexpected end of file
#+end_src

In this sample, this is due to the apostrophe in the header line ("Montant de
l'opération").

Any idea on how to:
- circumvent such problem?
- or, eventually, do this better?

Best regards,
  Seb
