that was the easy part... Now the question is "why"... (Its clear when you add anchors ^ and $ to the pattern).
This was a bug in my software. I converted characters from a source file into nodes (glue, glyph, ...) and had something like that:
for s in string.utfvalues(str) do
local char = unicode.utf8.char(s)
if s == 10 then
elseif match(char,"%s") then
and guess which kind of characters I was unable to display.
