as for your old version of TYPO3: be sure to have the database in a 
clean state of character encoding.
best would be to have all data in utf8-general.
the default character encoding can be set on different levels:
the database at all
each table
each field containing strings
also keep in mind the connection may be encoded in a different way.

you may need to convert your database to utf-8 if it uses other encoding 
as since 6.0 you need utf-8 anyway.

if your DB is utf8 make sure the connection also is utf8. in TYPO3 there 
is an initilization string for DB connections. make sure it is not set 
(remove from localconf.php) or set to
"SET CHARACTER SET utf8" (don't insert an empty string!)

on the other side:
if you create a new admin user from install-tool it should work as it is 
created with the same configuration as the login afterwards is tested. 
except there are issues independent from database: no cookies for that 
domain, wrong cookiedomain, no javascript, ...
