I have a CSV file which contains column names like "Désignation de la prestation". The rule I have for this never seemed to work so first I thought it was because of the white space but it seems that the french 'é' was the problem. When I write "Designation" the rule seems to match and the output shows up.
As I want to automate processing I cannot change that so would be great if that could be fixed. CSV file is UTF-8.
