I am looking at the possibility of encoding some of the Gutenberg
abbreviations into the golden ligatures collection.

However, when it comes to items such as a lowercase a with a horizontal line
over the top which is used as an abbreviation for am or an I am wondering
whether that character is, in fact, the same as U+0101 LATIN SMALL LETTER A
WITH MACRON or whether I need to code a Private Use Area code point for the
Gutenberg abbreviation.

Could someone advise on this please?

Suggestions for other ligatures and abbreviations to add into the golden
ligatures collection are also welcome.
