Incorrect Value when Passing LabVIEW Binary String Control Defaults from TestStand

Primary Software: TestStand
Primary Software Version: 4.1.1
Primary Software Fixed Version: N/A
Secondary Software: LabVIEW Development Systems>>LabVIEW Base Package

Problem:
When I specify to pass the default value for a LabVIEW string control in my TestStand module prototype, I do not get the correct string passed to my VI if I am passing the parameter as a binary string.  Why does this happen?

Solution:
There are two possibilities for the cause of this behavior.

1. Your binary string contains embedded null characters.  Traditionally, strings are terminated with a null character, so having a null character in your binary string causes incorrect parsing of the parameter.
2. You are passing your string as a binary string and are using a mult-byte language such as Chinese or Japanese.  Due to problems with conversion between multi-byte and unicode character representation, the default value is incorrectly passed.

Both of these problems are being investigated by National Instruments, and will be fixed in future versions of TestStand.
