You are right (I had not looked at the beginning of the file yet). I 
still do not understand what that character is meant for; maybe it has 
its use in modern Greek. Beccari's file works for ancient Greek as 
well, I often used it in the past.

At first sight, there is no need of rules about precomposed characters, 
but maybe there are some cases which I am not thinking of.

Nobody has an idea about these rules (in Beccari's file)?

% Initials with spirits
.<a2 .>a2 .<a|2 .>a|2 .<'a2 .>'a2 .<'a|2
.>'a|2 .<~a2 .>~a2 .<~a|2 .>~a|2
.<e2 .>e2 .<'e2 .>'e2
.<h2 .>h2 .<h|2 .>h|2 .<'h2 .>'h2 .<'h|2
.>'h|2 .<~h2 .>~h2 .<~h|2 .>~h|2
.<i2 .>i2 .<'i2 .>'i2
.<o2 .>o2 .<'o2 .>'o2
.<u2 .>u2 .<'u2 .>'u2
.<w2 .>w2 .<w|2 .>w|2 .<'w2 .>'w2 .<'w|2
.>'w|2 .<~w2 .>~w2 .<~w|2 .>~w|2

I do not see which such hyphenations should be prohibited.

Best wishes,
