Input Field with umlaut

Hello,

in our BSP we have an input field for a free text input. (HTMLB).

The umlaut (ä,ö,ü) in the field reflected in the value a #.

OnInputProzessing:

IDIF = 'zmtitle'.

INPUTFIELD ?= CL_HTMLB_MANAGER=>GET_DATA( REQUEST = REQUEST

ID = IDIF

NAME = 'inputfield' ).

VALUE = REQUEST->GET_FORM_FIELD( IDIF ).

Example:

Input: "für"

VALUE: "f#r"

Can somebody help me. Thanks.

Kind regards

Petra
