/ToUnicode spec violation

[sftse]

get_unicode_map includes a check that if the /ToUnicode key is a name, that it must be /Identity-H.
I have searched the pdf spec and checked a bunch of personal pdfs to see whether this is justified.
It seems to be a violation of the standard, is there an example of this occurring in practice?

I added db3a490 to make the intention here more clear.

From the PDF standard p.292
"This information can be provided as an optional ToUnicode entry in the font dictionary (PDF 1.2; see
9.10.3, "ToUnicode CMaps"), whose value shall be a stream object containing a special kind of CMap file
that maps character codes to Unicode values."

To clarify my question, it seems the PDF standard mandates the entry to be a stream object, is there an example where this entry was a name object?
