Ah. Bingo. soul.sty defines the fix font \SOUL at tt
(\font\SOUL at tt=ectt1000) and use it in various places when analyzing
the input. And obviously one gets problems as soon as words ends
with glyphs not existing in the font as this leads to boxes of width
0 and so soul thinks that there is no longer something to process. 

I can solve the problem with the euro sign by resetting the font to
latin modern typewriter with
\makeatletter \font\SOUL at tt="LMMono10-Regular"\makeatletter

With your greek characters you probably will need a greek fixed
width font.
