It warns as follows on -w option: ruby: warning: -K is specified; it is for 1.8 compatibility and may cause odd behavior ---------------------------------------- Feature #5206: ruby -K should warn https://bugs.ruby-lang.org/issues/5206#change-70479 * Author: drbrain (Eric Hodel) * Status: Closed * Priority: Normal * Assignee: matz (Yukihiro Matsumoto) * Target version: ---------------------------------------- When ruby is run with -K it changes the default encoding of all files even when that may be incompatible with the source. If many libraries are used -K may cause incorrect behavior. Now that we have the "coding:" magic comment ruby should warn if the -K flag is used and suggest that "coding:" magic comment be used instead. -- https://bugs.ruby-lang.org/ Unsubscribe:
