The character code positions are unused in the range 128-160 (which are the 
equivalent of the control characters, but with bit 7 set), so any characters
in that range are technically errors; if browsers do display them, the results 
will necessarily be system dependent. See:

Yes. Bizarrely, there is the lower case form of that character (255) but no 
upper case version. In fact, ISO-8859-[1 to 10] do not seem to have an 
uppercase Y umlaut.

Bear in mind that ISO-8859-1 is for Western European languages. See

At present, HTML is unable to accomodate other character sets, although this
will assuredly change in the future.
