Background
In novels, a lettrine is typically a letter. When writing prose, sometimes chapters begin with an opening quotation mark.
Problem
The quotation mark is stylized, rather than the first letter of the paragraph.
Code
Consider:
\setuphead[chapter][
after={\placeinitial},
page=no,
]
\starttext
\chapter{Harriet Tubman}
"Every great dream begins with a dreamer. Always remember, you have within
you the strength, the patience, and the passion to reach for the stars to
change the world.
\chapter{Eleanor Roosevelt}
Great minds discuss ideas; average minds discuss events; small minds
discuss people.
\stoptext
This produces:
Question
Without changing any text between \starttext and \stoptext, how would you change the \placeinitial macro to allow for changing the size and alignment of a quotation mark that is a chapter's first character---and format the first letter into a lettrine, as well?
