Just as something of a sanity test for me, and perhaps a test you could try for yourself, here's uparse with its argument taken from three different sources not associated with PerlMonks. 

$ perlbrew switch perl-5.32.0

$ perl -v | head -2 | tail -1
This is perl 5, version 32, subversion 0 (v5.32.0) built for cygwin-th

Copy-pasted from the Unicode PDF code chart "C1 Controls and Latin-1 Supplement (Range: 0080-00FF)": 

$ uparse äöü

============================================================
String: 'äöü'
============================================================
ä       U+E4     LATIN SMALL LETTER A WITH DIAERESIS
ö       U+F6     LATIN SMALL LETTER O WITH DIAERESIS
ü       U+FC     LATIN SMALL LETTER U WITH DIAERESIS
------------------------------------------------------------

Generated directly from a perl command: 

$ uparse `perl -C -e 'print "\x{e4}\x{f6}\x{fc}"'`

============================================================
String: 'äöü'
============================================================
ä       U+E4     LATIN SMALL LETTER A WITH DIAERESIS
ö       U+F6     LATIN SMALL LETTER O WITH DIAERESIS
ü       U+FC     LATIN SMALL LETTER U WITH DIAERESIS
------------------------------------------------------------

Generated separately then copy-pasted as an argument to uparse: 

$ perl -C -e 'print "\N{LATIN SMALL LETTER A WITH DIAERESIS}\N{LATIN SMALL LETTER O WITH DIAERESIS}\N{LATIN SMALL LETTER U WITH DIAERESIS}"'
äöü

$ uparse äöü

============================================================
String: 'äöü'
============================================================
ä       U+E4     LATIN SMALL LETTER A WITH DIAERESIS
ö       U+F6     LATIN SMALL LETTER O WITH DIAERESIS
ü       U+FC     LATIN SMALL LETTER U WITH DIAERESIS
------------------------------------------------------------
