Description: UTF8 can't handle \000
Details:

Trying to store \000 in a text field with UTF8 encoding causes an error. I
assume this is because Postgres is written in C, but it's still wrong. A
solution was suggested here:

"I can think of some ways the server could support it without extensive
changes .. e.g. use a modified UTF8 representation which stores \u0000 as
0xc0 0x80 internally"
