Maybe I am not the one to be speaking (since I haven't looked inside
phpMyAdmin), but I don't think the problem is phpMyAdmin.  utf-8 is a binary
stream.  so the fields you use with it should be MySQL types like
VARBINARY() or BLOB() or TINYBLOB or MEDIUMBLOB.
as binary data, it should be hexcoded, or at least fed through addslashes()
before it ends up being fed to the db, or use the mysqli functions
[including mysqli_prepare()] and variable binding.  I don't know what will
happen if a utf-8 stream ends up in SQL statements as table names.  There is
a chance one of those bytes might happen to be a quote character.  SQL is
ANSI, not utf-8 coded.

The problem you are having is not how do I put utf-8 text in, but instead,
how do I put a binary stream of data into a text field in phpMyAdmin.  The
answer is, of course, you do a workaround. phpMyAdmin's text fields were
made to work with text, not binary data such as utf-8.  that's the area you
are going to have to modify of course.

in PHPMyAdmin you can set the collation (charset), but you are limited to
what tthe database can handle. you can set a specific language, but that
doesn't include utf-8.  I looked in MySQL's share directory.
