Confirmed bug and when using OpenSSH for Windows 3.8.1p1-1 server and PuTTY 0.60 client. In this way i avoid to use cmd.exe of Windows 7, but problem persist

Way to avoid this bug: Use others mysql clients, especially with GUI, like SQLyog-10.3.0-0Community (tested and work ok) or HeidiSQL_7.0_Portable (tested and work ok), instead of original mysql command-line client (mysql.exe)

way to avoid : do not "chcp 65001". It is the same old story "doctor, it hurts when I do this..." :)

Vladislav, your way to avoid is the same as "do not use mysql". Please if you have constructive way to avoid this bug share it. Otherwise - shut up. This is place only for creative minds, not for trolls and diversion words ...

Could you please retest as described at http://dev.mysql.com/doc/refman/5.6/en/mysql-tips.html#windows-unicode-support: 1. Open a console window. 2. Go to the console window properties, select the font tab, and choose Lucida Console or some other compatible Unicode font. This is necessary because console windows start by default using a DOS raster font that is inadequate for Unicode. 3. Execute mysql.exe with the --default-character-set=utf8 (or utf8mb4) option. This option is necessary because utf16le is not supported as a connection character set. Please inform us about results. Thanks in advance.

I tested this on Windows 7 Home SP1. I first changed the shell font to Lucida Console as suggested. The default font produced strange characters for UTF8. What I find odd in the test below is that when invocking mysql with --default-character-set=utf8 the problem persists. Without --default-character-set=utf8 they display correctly. So using Lucida Console and not using --default-character-set=utf8 is a WORKAROUND for now. See the following attached file (utf8test.txt) for the test results.

From the internal analysis: This bug is due to the ANSI APIs being used to read the user data from console (ReadConsoleA). Fixing this bug needs conversion of the API from ReadConsoleA to ReadConsoleW. In addition to this conversion, we have to change internal buffers from 8 bit to wide char. This needs lot of changes and these changes are already implemented in 5.6 as part of work log 5331 (http://lists.mysql.com/commits/105379 ). We tested 5.6 version of client against 5.5 version of server, especially with respect to non ANSI characters. The 5.6 client worked as expected and the issue mentioned in this bug was also fixed. We are setting this bug to "won't fix" and we recommend to upgrade to 5.6 when that is available.
Description: Can't write in utf8 (65001 code page) via command prompt on Windows 7 and mysql 5.5.25a >mysqld.exe + cmd.exe + type "chcp 65001" => bye form command-line and exit mysql mysql> show variables like "char%" ---------------------------------+ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | ... How to repeat: 1) start mysqld 2) cmd.exe in windwos 7 3) chcp 65001 4) mysql -u root 5) try to type some symbols different from english alphabet => bye and mysql stops?!?!?!?!?! Each alphabet "абсдеий.....юя" is interpterer like "exit" commant from mysqld
