[tex-hyphen] Unicode code points or UTF-8 codes?

[Claudio Beccari]

How must be coded in a *.pat.txt file the address of a glyph thet has a 
pretty high code point?
For example suppose you want to set into a pat.txt file the combining 
acute accent: is had code point U+0301; speaking TeX or LuaTeX, must 
that glyph be inserted as ^^^^0301 or the utf-8 way ^^^^cc81 ?

Where and how do you assign it a non zero lccode?
