Hi,
You should be seeing your entered characters being displayed, not question marks.
This normally points to a misconfiguration somewhere - can you check that the following settings are in your 'my.cnf' config cile for MySQL:
[mysql]
…
default-character-set=utf8
…
and
[mysqld]
…
# The default character set that will be used when a new schema or table is
# created and no character set is defined
default-character-set=utf8
…
