ASCII extended characters won't be written/coded properly :o(((

Hello.

Nope. é is 0xE9 in both ISO-8859-1 and ISO-8859-15. Your controller
most probably expects IBM437, as that's where é is encoded as 0x82.

That's because you're using a *.UTF-8 locale (and rightly so).

It's a problem with the terminal. You have to recode
the files from UTF-8 to IBM437, for example with

$ iconv -f UTF8 -t IBM437 -o recoded.file original.file
