Problem when Updating version of gatling to 3.5.1

[ghazouani_nada]

Hello,
when i updated gatling version from 3.3.1 to 3.5.1 as well as the degatling-plugin.version version from 3.0.5 to 3.1.1, I encountered a problem of failure in the build of scenario as shown in the screenshots below

Knowing that with the old version (3.3.1) the scenario works well and the buid has succeeded
I need help please why with the new version failed?

thanks in advance.

It looks like your csv file uses an encoding different from the one configured in gatling.conf (utf-8 by default).

Thank you for your response.
But how w i can solve the problem and use the default encoding utf-8 ?

Use a text editor, select utf-8 and save back.
