It is specified as a translation by unicode.org. This is used for two options:

1. Options / metadata / Punctuation to ASCII
2. Options / File naming / Replace non ASCII characters

Since \u201A is NOT an ascii character and cannot translate to ascii, that is why it is in the list.

However, if you could explain (for those of us who have no idea where a low-9 quotation mark actually is) why you think it should not be translated or what you think it should be translated to instead we can certainly tweak this.
