error rendering output of tree

[nkh]

$> tree | moar

spurious '??' are displayed among the tree lines

[walles]

moar expects its input to be UTF-8 encoded text.

Unprintable / invalid characters are rendered as ? (see below).

You have two options:

• Resolve the root cause by making tree output valid and printable UTF-8 only
• Try working around the problem using --render-unprintable whitespace

I will consider documenting this better before closing this issue.
