Hi, the following 3 examples all crash perl on Windows: perl -e "use open qw{:encoding(UTF-8) :std}; fork; " perl -e "open $f, '>:encoding(UTF-8)', 'temp.txt'; fork" perl -e "use utf8::all; fork" tried with both Strawberry Perl 5.12.3 and 5.16.2 with the same results. See this thread http://perlmonks.org/?node_id=1009989 especially this post: http://perlmonks.org/?node_id=1010004 (I tried to file a bug with perlbug but I think it never left my Windows machine). Gabor ps. They did not segfault on Linux.Thread Next
