;; Warning: If you deal with Unicode characters often, note that some do not ;; fit into a single 16-bit Java char. Yes, such Unicode characters exist. ;; The JVM encodes them in strings in memory using UTF-16, as 2 consecutive ;; 16-bit values, each with their own separate index in the string's array ;; of chars. ;; https://en.wikipedia.org/wiki/UTF-16 ;; clojure.string/capitalize should not be used for such strings, as it ;; operates by feeding the first 16-bit Java char for capitalization, and the rest ;; of the Java chars for converting to lower case. ;; I wouldn't bother filing (another) bug on Clojure for this, since it is ;; unlikely to change in this regard. If you are dealing with many languages ;; in the Unicode character set on a regular basis, then you likely ;; want to use a library like ICU4J, which is much more sophisticated in its ;; capabilities than anything built into Clojure. ;; ICU4J (also ICU4C): http://site.icu-project.org
