Maksim,

What UNIX are you using where that's a valid username? If Linux, what 
distribution?

Not disparaging it, just wondering. I agree that this is not how zsh 
should be behaving. Are other shells (e.g. bash, Korn, tcsh) behaving 
correctly?

In English, we call the script used in Russia, Ukraine, Belarus, and a 
few other countries (including most internal vassals of Russia, as well 
as Bulgaria, Serbia (sometimes), Montenegro, Mongolia, Tajikistan, and 
until recently Kazakhstan) to write their native languages "Cyrillic", 
not "Cyryllic". Your English spelling and grammar is otherwise entirely 
acceptable.

    Hello, this is the first time I am using mailing lists, don't be mad
    at me if I do something wrong.
    Sorry for errors, English is not my native language.


    I found a bug in zsh:

    If I add this line to the top of _/etc/passwd_ (before the "root"
    line, also works with other UIDs):

        Студент:x:0:0:root:/home/Студент:/usr/bin/zsh


    After logging in as "root" (so environment will be good, as in this
    case "root" line is used for login), and running this commands:

        mkdir -p '/home/Студент'
        env -i LANG=C.UTF-8 zsh -fc 'cd; echo "$USERNAME | ${(%):-%n} |
        $LOGNAME"'


    I will get:

        �т��ент | Ст\M-Q\M-p\M-4ент | Студент


    Instead of:

        Студент | Студент | Студент


    As we can see, _$LOGNAME_ is fine, but _$USERNAME_ and _%n_ are bad.

    -----------------------------

    Also, probably related, _zcompile_ don't work on cyryllic paths:

        touch '/home/Студент/.zc/.zcompdump-5.9'
        zcompile '/home/Студент/.zc/.zcompdump-5.9'


    Results in:

        zcompile: can't write zwc file: /home/Студент/.zc/.zcompdump-5.9.zwc
