What they probably mean is the name as it’s spelled in the MRZ (the ‘Machine Readable Zone’, the two lines at the bottom of the passport), which is also stored in data group 1 in the embedded chip. Passports can also contain the full name in UTF-8 in data group 11, but this is an optional field.

The MRZ can only contain the characters A-Z (uppercase), 0-9 and <. ICAO document 9303-3 describes conventions for transliteration of other characters into this limited character set.
