Cart update and remove buttons don't work

Hello,
the mini cart works fine but in the cart, the buttons update and remove don't work.
Some categories and products names contain accents (french language) and commas.
Do you think it may cause troubles with the buttons?
What can I do to fix the bug?
Sincerily,
Dominique

Hello Dominique,
