Ali Cehreli <acehr...@yahoo.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |acehr...@yahoo.com --- Comment #3 from Ali Cehreli <acehr...@yahoo.com> --- It looks like I am outdated on this issue because I had never heard of the 0069 0307 sequence before H. S. Teoh brought the following change to my attention: https://github.com/D-Programming-Language/phobos/pull/3848 I've learned since then that the two-character sequence should be the default but TR locale should still use just 0069. According to the following quote, Java 7 behaves differently depending on locale: http://grepalex.com/2013/02/14/java-7-and-the-dotted--and-dotless-i/ <quote> CODE LOWER TITLE UPPER LANGUAGE 0130; 0069 0307; 0130; 0130; 0130; 0069; 0130; 0130; tr; 0130; 0069; 0130; 0130; az; Entries with a language take precedence over those without, so in my JVM where the default locale is English, the first row of the mapping is used, which lines-up with the codepoints that we saw outputted in our Java 7 example. Therefore to make Java do the right thing here for Turkish, we need to explicitly specify the Turkish locale (“tr” is the ISO 639 alpha-2 language code for Turkish) to the toLowerCase method </quote> Should std.uni be locale-aware? --
