Issue #18590 has been updated by mame (Yusuke Endoh). Status changed from Open to Closed Fixed at commit:bda4d91f0599a8e2d278bc13660a5576d4ced353 ---------------------------------------- Bug #18590: String#downcase and CAPITAL LETTER I WITH DOT ABOVE https://bugs.ruby-lang.org/issues/18590#change-97902 * Author: andrykonchin (Andrew Konchin) * Status: Closed * Priority: Normal * Assignee: duerst (Martin Dürst) * ruby -v: 3.1.0p0 * Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN ---------------------------------------- Downcasing for "İ" character works in an unexpected way: ```ruby 'İ'.downcase => "i̇" ``` Expected result - downcasing should return "i". Instead, it returns small "i" and additional "dot" character: ```ruby 'İ'.downcase.chars => ["i", "̇"] ``` According to the standard Unicode case mapping character 'İ'(0130) maps to lowercased 'i' (0069). ``` 0130;LATIN CAPITAL LETTER I WITH DOT ABOVE;Lu;0;L;0049 0307;;;;N;LATIN CAPITAL LETTER I DOT;;;0069; ``` https://www.unicode.org/Public/UCD/latest/ucd/UnicodeData.txt -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request@ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
