For CI, it appears that Ubuntu 20.04 provides utf8proc 2.5, but the isupper/islower functions are not provided until 2.6: https://juliastrings.github.io/utf8proc/releases/ Meanwhile, RTools35 is using utf8proc 2.4; it builds utf8proc from source due to some other issue, but I believe it's using the system headers anyways looking at the compiler command since the system headers come before the self-built utf8proc ones. I think bumping the minimum utf8proc version and fiddling with the build flags so that the utf8proc headers take precedence will be needed. -- This is an automated message from the Apache Git Service.
