Nextion firwares not compatibles with accented characters.

[Francis663]

I found that characters are missing in the Nextion display when the french language (fr) is selected.
I had to install the Nextion editor to load the HMI file and change the setting from 'ASCII' to 'ISO-8859-1'.
I used the Nextion Font editor to generate ISO-8859-1 fonts, replaced MK32 font by Lucida Console font with size 32. The I swapped ASCII fonts (95 chars) by ISO-8859-1 fonts (227 chars).
Exported .tft file and loaded in the display: working fine!
I suggest to generate HMI and TFT files with ISO-8859-1 codings.
