No, I have been using beacon package for few years now.

Those characters are in the buffer, not overlay. And they are not in the
first 2874 characters.
Here are the roughly first 3000 chars of that Org buffer: http://ix.io/1Hgv
Note that at many places in that snippet, I have "=>" characters which I
replace with a unicode symbol via prettify-symbols mode. E.g. "=>" is
replaced with:
position: 5434 of 8347 (65%), column: 35
character: (displayed as ) (codepoint 59428, #o164044,
#xe824)
charset: unicode (Unicode (ISO10646))
code point in charset: 0xE824
syntax: w which means: word
category: L:Left-to-right (strong)
to input: type "C-x 8 RET e824"
buffer code: #xEE #xA0 #xA4
file code: #xEE #xA0 #xA4 (encoded by coding system utf-8-unix)
display: by this font (glyph code)
xft:-unknown-PragmataPro-normal-normal-normal-*-17-*-*-*-*-0-iso10646-1
(#x11D5)
Character code properties: customize what to show
general-category: Co (Other, Private Use)
decomposition: (59428) ('')
There are text properties here:
fontified nil
Would that be causing a problem?
Here is my entire set of ligature substitution using prettify-symbols:

Understood. Thank you, will build with -O0 -ggdb3 going forward.
