[pdftex] PdfTeX - letter é catcode def

[👨🏻 🦰 Vincent Breton]

Hi Karl,

Thank you very much for you reply. The answer you gave me is perfectly
appropriate for me
I will warn my readers about pdftex knowing that LuaTeX and XeTeX are 
working fine with UTF-8. If I have time I will try to play with the
table of chars but for the moment my skills are not enough evolved to do
that.

Best regards
