Perl Unicode Cookbook: Unicode Text in DBM Files (the easy way)
℞ 43: Unicode text in DBM hashes, the easy way Some Perl libraries require you to jump through hoops to handle Unicode data. Would that everything worked as easily as Perl’s open pragma! For DBM files, here’s how to implicitly…

Perl Unicode Cookbook: Unicode Text in Stubborn Libraries
℞ 42: Unicode text in DBM hashes, the tedious way While Perl 5 has long been very careful about handling Unicode correctly inside the world of Perl itself, every time you leave the Perl internals, you cross a boundary at…

Perl Unicode Cookbook: Case- and Accent-insensitive Locale Comparisons
℞ 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,…

Perl Unicode Cookbook: Case- and Accent-insensitive Comparison
℞ 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,…

Perl Unicode Cookbook: Unicode Locale Collation
℞ 37: Unicode locale collation As you’ve already seen, Unicode-aware sorting respects Unicode character properties. You can’t sort by codepoint and expect to get accurate results, not even if you stick with pure ASCII. The world is a complicated place….

Perl Unicode Cookbook: Case- and Accent-insensitive Sorting
℞ 36: Case- and accent-insensitive Unicode sort The Unicode Collation Algorithm defines several levels of collation strength by which you can specify certain character properties as relevant or irrelevant to the collation ordering. In simple terms, you can use collation…
