℞ 40: Case- and accent-insensitive locale comparisons You now know how to compare Unicode strings while ignoring case and accent differences. This approach uses the standard Unicode collation algorithm. To perform a similar comparison while respecting a specific locale’s rules,…

℞ 39: Case- and accent-insensitive comparisons As you’ve noticed by now, many Unicode strings have multiple possible representations. Comparing two Unicode strings for equality requires far more than merely comparing their codepoints. Not only must you account for multiple representations,…

℞ 38: Making cmp work on text instead of codepoints Even with Perl 5.12’s “unicode_strings” feature, some of Perl’s core operations do not perform as expected on Unicode strings by default. For example, how is the cmp operator to know…
