Both ncdump and ncgen can handle Unicode names in files. Example ncdump output:
dimensions: pressure = 10 ; pressão = 10 ; ciÅ›nienie = 10 ; налÑгане = 10 ; 压力 = 10 ; πίεση = 10 ; давление = 10 ; ì••ë ¥ = 10 ; variables: float πίεση(πίεση) ; πίεση:standard_name = "air_pressure" ;
NetCDF-4 note:
In netCDF-4 ncdump and ncgen, Unicode symbols are also permitted in
names for groups, user-defined types, compound-type members, and
enumeration symbols.
