I try to understand whether "E" + CGJ + "s" + CGJ + "c" + U+20E3
COMBINING ENCLOSING KEYCAP should produce a representation of an
"Esc" key in plain text (given an appropriate font rendering
I refer to the phrase "The combining enclosing marks apply to a
preceding default grapheme cluster." (printed edition of "The Unicode
<standard V4.0", p.188).
Does the Combining Grapheme Joiner (CGJ, U+034F) constitute a grapheme
cluster in the sense of UAX 29 "Text boundaries"?
I did not find any evidence there. (Maybe I overlooked something or
searched in the wrong place?)
Or is producing multi-letter key representations in plain text done
by another mechanism as CGJ (e.g. ZWJ), or is it subject to higher level
protocols at all?
