Date: 2019-03-21T23:33:08+00:00 Subject: [ruby-core:91918] [Ruby trunk Bug#15718] YAML raises error when dumping strings with UTF32 encoding Issue #15718 has been updated by rubenochiavone (Ruben Chiavone). I see. There are other regexp based code similar to what `Psych::Visitors::YAMLTree.visit_String` does. Not sure if testing for encoding before matching as I initially proposed is the way to go. What else do you suggest that could be a fix? Maybe convert it to `US_ASCII` or skip non-`US_ASCII` text altogether? ---------------------------------------- Bug #15718: YAML raises error when dumping strings with UTF32 encoding https://bugs.ruby-lang.org/issues/15718#change-77250 * 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 `
