If you copy config.php.default and then install from CLI you won't have emoji support because this line is missing
If you are installing a brand new XenForo, rather than upgrading from an existing version, you may include emoji support from the outset. The installer will add the necessary line to your src/config.php file automatically, if you allow the installation system to build your config file for you.
I, and I'm sure others, would expect the file labelled as "default" to have similar contents to what you would get by having the install process build it for you. I think we're fine to leave it up to XF to determine whether this is intentional or notOnly if if you allow the installation system to build your config file for you, otherwise you need to add it yourself.
Indeed.I think we're fine to leave it up to XF to determine whether this is intentional or not
Any changes made as a result of this issue being resolved may not be rolled out here until later.Ensure we include the fullUnicode default for new installs in the config.php.default file.
