Hi Ken!

Tried to find a general solution to the problem reported in Re: uparse - Parse Unicode strings.

Short explanation of the problem:
There are two basic ways to get correct UNICODE input from the elements in @ARGV:

Either may be used, but not both.

A script that expects UNICODE data from @ARGV cannot easily detect if the implicit decoding is in effect, especially because -CAL makes the behaviour locale-dependent.

The best solution I could find is to check if the data in question is already marked to be in UTF-8. Encode::is_utf8 (or the equivalent utf8::is_utf8) may be used to check this flag, which results in a small modification to your script: 

diff --git a/uparse b/uparse
index f5edb92..b05e12a 100755
--- a/uparse
+++ b/uparse
@@ -23,11 +23,11 @@ use constant {
     NO_PRINT => "\N{REPLACEMENT CHARACTER}",
 };
 
-use Encode 'decode';
+use Encode qw(decode is_utf8);
 use Unicode::UCD 'charinfo';
 
 for my $raw_str (@ARGV) {
-    my $str = decode('UTF-8', $raw_str);
+    my $str = is_utf8($raw_str) ? $raw_str : decode('UTF-8', $raw_str
+);
     print "\n", SEP1;
     print "String: '$str'\n";
     print SEP1;

What do you think about this?
