SHIMA Tatsuya commented on ARROW-18123:
---------------------------------------
Thanks for your comment.
But does it explain that relative paths can be used if they do not contain
multibyte characters?
The sample code appears to use relative paths.
And, the documentation I am looking at does not seem to have a link to that
detailed explanation.
