I have to display French on a display with fixed/limited character set. It is missing all the capital letters with diacritics. Specifically:
À Â È Ê Ë Î Ï Ô Ù Û
Do the graves only indicate pronunciation or or also semantics? Would it be fine to just substitute those chars with
A I E O U or do I need to take special considerations?
PS: The context is pretty specific. The display is used on campsites to control devices like showers, door access etc. So it displays messages like "Remaining credits/time", "Access granted", "Press button to start/stop" and things like that. The display has two lines with 16 chars each, so text has to be kept brief.
It would be OK for me if it is just bad practice to omit the diacritics. It may not be OK, if chances are high, that people get confused by wrong meaning.
