If I translate the following sentence from de to en in InstantTranslate at a client:
Please note, I will be arriving with my family (Max Müller & Manuel Müller) a week early and will be vacationing in Singapore or Malaysia the week before.

then t5memory throws an error
E0318 18:07:13.069651 9 OTMTMXIE.cpp:3234] , with body =

    lb:

{ Error during FUZZY request, id = 40867 , for memory "TM1121-ID113-XXX_TM_DE_EN"}

The error in t5memory is thrown because of the "&".

In my opinion, however, this should not arrive in t5memory at all, but as & - i.e. as valid xml.

This also works in the editor (just tested). But not in InstantTranslate.

So this should be done the right way for all xml special chars.
