Validate reports unexpected NaN error for ASCII_String fields

[jennifergward]

Checked for duplicates

No - I haven't checked

🐛 Describe the bug

We realize this won't be addressed until all the NaN issues are sorted out, but validate is reporting an error for values of "NaN" in ASCII tables that have fields defined as ASCII_String. NaN is not allowed for data type ASCII_Real. We can't find a statement in the SR that says NaN is not allowed for ASCII_String.

🕵️ Expected behavior

We didn't expect to see this error for ASCII_String fields.
