Description mail_of_sergey 2010-01-18 11:40:06 UTC 
I connect to remote FreeBSD machine via via Putty.
I add new user by adduser script.
I type russian letters at "full name" field and delete one russian letter
by backspace key and type new russian letters.
At this case the adduser script shows the "full name" field with bogus symbol:
Password   : <blank>
Full Name  : &#1051;<D0>&#1080;&#1085;
Uid        : 1180

The bogus symbol is in brockets. I see bogus symbol D0 and D1.
This bogus symbol will be written to GEOS field of password file. :(


According to UTF-8 encoding table and Unicode characters
(http://www.utf8-chartable.de/unicode-utf8-table.pl) (don't forget select
cyrllic page) any russian letter is presented by two bytes. The first
byte is D0 (or D1 for some letters)

It is looks like the backspace key deleted only one byte of two-byte encoding.

How-To-Repeat: 1. run adduser
2. Start to type full name by russian letters (or other two-byte presented
   letters)
3. Delete one letter by backspace key
4. Continue type letters
5. Continue add user.
6. tail /etc/passwd
