Dissector: ignore “0x00” in a string (FT_STRING)?

Hi,

I am writing a custom Wireshark dissector which needs to show some strings. Let me say there is some hex code like "48 65 6c 6c 6f" which is "Hello". This is interpreted fine by using FT_STRING in the hf_ declaration. If this hex codes contain something like "48 65 6c 6c 6f 00 48 65 6c 6c 6f", the second "Hello" gets not displayed in the UI. I assume it is because of the "00" in between. Is there a way to convince Wireshark not to interpret "00" as a string termination but continue displaying the string?

Thanks, hhhannes
