### Half-way solution
Some possible half-way solution would be:
* Assume non-ASCII class names are UTF-8 * Raise on dump for class names with non-UTF8 compatible class names.
It's far from ideal though.
I think this would be a pretty good solution actually, it seems very unlikely to have class names which can't be encoded in UTF-8. ---------------------------------------- Bug #20009: Marshal.load raises exception when load dumped class include non-ASCII https://bugs.ruby-lang.org/issues/20009#change-113198 * Author: ippachi (Kazuya Hatanaka) * Status: Open * ruby -v: ruby 3.2.2 (2023-03-30 revision e51014f9c0) [arm64-darwin22] * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- ## Reproduction code ```ruby class Cクラス; end Marshal.load(Marshal.dump(Cクラス)) ``` ## Actual result ``` <internal:marshal>:34:in `load': undefined class/module C\xE3\x82\xAF\xE3\x83\xA9\xE3\x82\xB9 (ArgumentError) from marshal.rb:2:in `<main>' ``` ## Expected result Returns `Cクラス` ## Impacted area An exception is raised in Rails under the following conditions * minitest is used with default settings * Parallel execution with parallelize * test class names contain non-ASCII characters The default parallelization uses DRb, and Marshal is used inside DRb. ## Other After trying various things, I thought I could fix it by making `rb_path_to_class` support strings containing non-ASCII characters, but I couldn't find anything more than that. -- https://bugs.ruby-lang.org/
