Hello, It seems that makeinfo does not support non-ASCII characters in directory names added to the @include search path.
If this is intentional, I could not find any trace of it in the documentation. If it's not documented, it might be useful to do so. For an example of a downstream issue, see https://octave.discourse.group/t/segfault-when-building-the-documentation/2233/14 Best regards, Gaël Bonithon
