There is one for zsh called mapfile, but it's a module and must be loaded to use, and it's not a function unlike readarray.

bash: string variable contains asterisk. how to use this variable for searching etc with grep, sed?
For grep, you can use -F to use fixed strings instead of regexes. For sed, it's much more complex. I'd probably switch to Perl which can help you with its \Q/quotemeta function.

^? is the byte 127 = 0x7f, which is commonly sent by the Backspace key (unless it's set to send ^H and the Delete key is set to ^?).

Shell one-liner for batch renaming music albums folders according to regexp – “zsh: missing identifier after `+'”
In zsh, you'd use zmv to rename files:
autoload -Uz zmv # best in ~/.zshrc
zmv -n '(*PESTE NOIRE*-)(*) \((<1900-2100>)\)' '$1 $3$2'
Remove the -n (dry-run) to actually do it.

zsh -z test meaning of "+x"
This isn't due to test, but on zsh variable expansion.
The construct ${foo+bar} will return bar if $foo is set.
So, for example:
zsh% unset foo
zsh% echo ${foo+bar}
zsh% foo=
zsh% echo ${foo+bar}
