Problem about display description of data element in search help screen

[Former Member]

Dear all,

We are using ECC6.0 system. I create a language key vi (Vietnamese) using language imports/supplements from English language.

I use TCode: CMOD to change description of a data element to Vietnamese language (Hãy đến Việt nam). When using search help of this data element, description of this data element is 'Hãy d?n Vi?t nam'.

Please view the problem here:

Who can give me some idea for the problem?

Thanks
