Cannot treat backquote ` well

The following gives an error:

dict1 = YAML.load(text)

# write YAML

YAML.write(io, dict1)

Heh - apparently github has issues with it too. Can you just confirm it's a bug using another YAML parse (plenty of web-based ones)?

Parsing is well but there is a bug in writing. From https://www.bairesdev.com/tools/json2yaml/
