Description:
I created a webpage, which accesses a MySQL database. Server IIS, language ASP.
Created a test Table with 4 fields:
id
text_1  text
text_2  varchar(100)

Conditions:
- default charset and collation: UTF8, UTF8_general_ci, TEXT type has own UTF8 and UTF8_general_ci collation settings.
- the html form control for each field is TEXTAREA.

Inserted special Hungarian characters into both field types and the result:

In case of TEXT fields, the storing and retrieving shows the followings:
- é -> OK.
- á -> OK.
- ő -> UTF C5 91 incorrectly stored: C3 B5
- ű -> UTF C5 B1 incorrectly stored: C3 BB

In case of VARCHAR fields, the storing and retrieving is done OK, without miscoding.

How to repeat:
Repeat as described above.

The storing is done through ODBC 5.1
