I  think something like this


-- begin
-- save this in symbols.lua
Symbols={['BOX DRAWINGS LIGHT HORIZONTAL'] = 9472,
['BOX DRAWINGS HEAVY HORIZONTAL'] = 9473,
['BOX DRAWINGS LIGHT VERTICAL'] = 9474,
['BOX DRAWINGS HEAVY VERTICAL'] = 9475,
['BOX DRAWINGS LIGHT TRIPLE DASH HORIZONTAL'] = 9476,
['BOX DRAWINGS HEAVY TRIPLE DASH HORIZONTAL'] = 9477,
['BOX DRAWINGS LIGHT TRIPLE DASH VERTICAL'] = 9478,
['BOX DRAWINGS HEAVY TRIPLE DASH VERTICAL'] = 9479,
['BOX DRAWINGS LIGHT QUADRUPLE DASH HORIZONTAL'] = 9480,
['BOX DRAWINGS HEAVY QUADRUPLE DASH HORIZONTAL'] = 9481,
['BOX DRAWINGS LIGHT QUADRUPLE DASH VERTICAL'] = 9482,
['BOX DRAWINGS HEAVY QUADRUPLE DASH VERTICAL'] = 9483,
['BOX DRAWINGS LIGHT DOWN AND RIGHT'] = 9484,
['BOX DRAWINGS DOWN LIGHT AND RIGHT HEAVY'] = 9485,
['BOX DRAWINGS DOWN HEAVY AND RIGHT LIGHT'] = 9486,
['BOX DRAWINGS HEAVY DOWN AND RIGHT'] = 9487,
['BOX DRAWINGS LIGHT DOWN AND LEFT'] = 9488,
['BOX DRAWINGS DOWN LIGHT AND LEFT HEAVY'] = 9489,
['BOX DRAWINGS DOWN HEAVY AND LEFT LIGHT'] = 9490,
['BOX DRAWINGS HEAVY DOWN AND LEFT'] = 9491,
['BOX DRAWINGS LIGHT UP AND RIGHT'] = 9492,
['BOX DRAWINGS UP LIGHT AND RIGHT HEAVY'] = 9493,
['BOX DRAWINGS UP HEAVY AND RIGHT LIGHT'] = 9494,
['BOX DRAWINGS HEAVY UP AND RIGHT'] = 9495,
['BOX DRAWINGS LIGHT UP AND LEFT'] = 9496,
['BOX DRAWINGS UP LIGHT AND LEFT HEAVY'] = 9497,
['BOX DRAWINGS UP HEAVY AND LEFT LIGHT'] = 9498,
['BOX DRAWINGS HEAVY UP AND LEFT'] = 9499,
['BOX DRAWINGS LIGHT VERTICAL AND RIGHT'] = 9500,
['BOX DRAWINGS VERTICAL LIGHT AND RIGHT HEAVY'] = 9501,
['BOX DRAWINGS UP HEAVY AND RIGHT DOWN LIGHT'] = 9502,
['BOX DRAWINGS DOWN HEAVY AND RIGHT UP LIGHT'] = 9503,
['BOX DRAWINGS VERTICAL HEAVY AND RIGHT LIGHT'] = 9504,
['BOX DRAWINGS DOWN LIGHT AND RIGHT UP HEAVY'] = 9505,
['BOX DRAWINGS UP LIGHT AND RIGHT DOWN HEAVY'] = 9506,
['BOX DRAWINGS HEAVY VERTICAL AND RIGHT'] = 9507,
['BOX DRAWINGS LIGHT VERTICAL AND LEFT'] = 9508,
['BOX DRAWINGS VERTICAL LIGHT AND LEFT HEAVY'] = 9509,
['BOX DRAWINGS UP HEAVY AND LEFT DOWN LIGHT'] = 9510,
['BOX DRAWINGS DOWN HEAVY AND LEFT UP LIGHT'] = 9511,
['BOX DRAWINGS VERTICAL HEAVY AND LEFT LIGHT'] = 9512,
['BOX DRAWINGS DOWN LIGHT AND LEFT UP HEAVY'] = 9513}
--end

%%%% save this in t.tex
%% UnicodeSymbols was made by saving Unicode.otf with fontforge
\ctxluafileload{symbols.lua}{}
\definefont[WhatEver][UnicodeSymbols at 100pt]
\starttext
{\WhatEver\unicodechar{\ctxlua{tex.sprint(Symbols['BOX DRAWINGS UP
LIGHT AND LEFT HEAVY'])}}}
\stoptext

The idea is to use a normative name
(Am I wrong if I said that 'BOX DRAWINGS UP LIGHT AND LEFT HEAVY' is
normative ?)
