I don't get the hyphen if I put


\XeTeXinputnormalization=1


in the preamble and write the offending word as


βαίνο


i.e., inserting a COMBINING ACUTE TONE MARK (U+0341) after the iota
(the software used for this message probably does the combination by itself). The
same if I use COMBINING ACUTE ACCENT (U+0301). But no, not with \char.


Ciao
Enrico
