Using certain Unicode characters causes $.evalFile to throw “Cannot convert to <file path>” error

The simplest example is this:

alert(" \u00A0");

I’ve confirmed that the following characters cause the error:
\u00A0, \u180E, \u2001–\u200D, \u205F
However, it seems that there are several other Unicode characters that also trigger this issue.

I would like to request a fix for this bug.
