Hello Juan, Thanks for your explanation. It is clear that C source files should be only in single-byte ASCII with charcode < 127 to avoid any problem with the build tools. My previous question is actually not related to character encoding for C source files, but rather for the character encoding in the scancode tables. When you say " Replacing 'é' wilth '\202'", what exact pagecode with single bytes are you refering to ? The link you provided has no reference to any official pagecodes. Should it be IBM 437 or 850, Windows 1252, IANA 8859-1 ? This is important to ensure consistency between the character encoding by the keyboard driver and the character rendering in the display driver, because glyph bitmaps are indexed on the character code. One needs this information to fix the tables in keys-*.h. MFLD 2016-05-18 22:27 GMT+02:00 Juan Perez-Sanchez <lithoxs@xxxxxxxxx>: > Hello Marc: > > You are right. I should say "grep".
