print length("\N{LATIN CAPITAL LETTER E WITH ACUTE}ric");
[download]

and it's reporting syntax error.

You need something like this before you can use named Unicode characters: `use charnames ':full';` Improve your skills with Modern Perl: the free book.	[reply] [d/l]

By syntax error, do you mean the following? `Constant(\N{LATIN CAPITAL LETTER E WITH ACUTE}ric) unknown: (possibly +a missing "use charnames ...") at - line 1, within string Execution of - aborted due to compilation errors.` [download] If so, like the message says, it's because you need to add `use charnames ':full';`. If not, could you be more specific? Maybe your version of Perl predates `\N{}`? PS — charnames will be loaded automatically when needed in 5.16.	[reply] [d/l] [select]
