WDYT? What about: ``` YAML.dump("Hello\nWorld".force_encoding('UTF-32LE')) ``` or other strings like `"123"` that need special formatting? ---------------------------------------- Bug #15718: YAML raises error when dumping strings with UTF32 encoding https://bugs.ruby-lang.org/issues/15718#change-77249 * Author: marcandre (Marc-Andre Lafortune) * Status: Open * Priority: Normal * Assignee: * Target version: * ruby -v: 2.6.2p247 * Backport: 2.4: UNKNOWN, 2.5: UNKNOWN, 2.6: UNKNOWN ---------------------------------------- ```shell ruby -r yaml -e "p YAML.dump( ''.force_encoding('UTF-32LE') )" Traceback (most recent call last): 4: from -e:1:in `
