Edit report at https://bugs.php.net/bug.php?id=81616&edit=1 ID: 81616 Updated by: cmb@php.net Reported by: gblanchet at cofomo dot com Summary: Windows binaries comes by default with libidn instead of libidn2 Status: Not a bug Type: Bug Package: cURL related Operating System: Windows PHP Version: 8.0.12 Assigned To: cmb Block user comment: N Private report: N New Comment: Oh, forgot to link to our configure line: <https://github.com/winlibs/winlib-builder/blob/8167993484d58b390d93f26f660953d9fec59875/.github/workflows/curl.yml#L46> Previous Comments: ------------------------------------------------------------------------ [2021-11-12 14:11:08] cmb@php.net As far as I know, only Windows IDN APIs are supported on Windows[1]. These are not disabled for our builds (there is an apparently erroneous USE_IDN=yes, but since ENABLE_IDN defaults to yes, that shouldn't be an issue). So there's nothing we can do.

WHAT ACTUALLY HAPPENED: I realized cURL was using the old IDNA2003 protocol instead of the new one: IDN2008 because the German letter "ß" was translated to "ss" in the a-label queried. I check the curl_version() and I found the cause: on Windows, PHP8 seems to be bundled with libidn instead of libidn2. Please ensure the cURL extension is compiled with libidn2 instead of libidn to generate the Windows binaries. Test script: --------------- php > var_dump(curl_version()); php shell code:1: array(16) { [...] 'version' => string(6) "7.76.1" [...] 'libidn' => string(0) "" [...] } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=81616&edit=1
