[Oberon] Representation of Latin Small Letter U with diaeresis in a source Text and a text.

[peter at easthope.ca]

Hi,

Most source Texts and source texts which originated at ETHZ begin with 
a line similar to this. (* ETH Oberon, Copyright 2001 ETH Zuerich ...

I've seen at least three representations of "Latin Small Letter U with 
diaeresis", as Unicode describes it.

(1) "ue" which Europeans might consider a kludge.

(2) "ü" which a hexadecimal editor displays as FC.  According to 
Wikipedia, this is from the "C1 Controls and Latin-1 Supplement" of 
Unicode.

(3) "ü" which a hexadecimal editor displays as C3 BC.  A Microsoft 
encoding?

 (4) "&#uuml;"  the character entity reference of Unicode.
 
 How do Europeans prefer to see the accented characters represented in 
 an Oberon Text and in an ASCII text for a source of an Oberon system?
 
 Thanks,                          ... P.L.
