I have to display Spanish on a display with fixed/limited character set. The display is used 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. It is missing the capital letters with acute accent:
Á Í Ó Ú
I have zero Spanish knowledge so the question is:
Do the acute accents only indicate pronunciation or or also semantics? Would it be fine to just substitute those chars with
A I O U or do I need to take special considerations?
