[Biblical-languages] Apostrophe / Coronis

I see I misunderstood things slightly because I did not refer to the
technical manual for the old non-Unicode SIL Greek Font System
(http://www.sil.org/computing/fonts/silgreek/index.html). In fact this makes
it clear that, in both the Basic Greek and Composite Greek encodings, the
apostrophe should be encoded as x40 (@), and the smooth breathing - isolated
in the Composite Greek encoding and also before upper case vowels in the
Basic Greek encoding - should be encoded as x48 (H). And the conversion
table SIL Galatia - Unicode.cct was clearly designed with this distinction
in mind, and to work with the Composite Greek encoding. So the main change
needed is to change the output code for apostrophe from 1FBD to 2019. The
current table treats isolated accents breathings as errors - while
paradoxically accepting combinations of these without base letters.
I attach a version of this table amended to change the output for the
apostrophe and correct the other small omissions.
