Hi, I was hoping you would accept this patch to typo-tal.lua:
index a67cd0a..100d95d 100644
--- a/tex/texmf-context/tex/context/base/mkiv/typo-tal.lua
+++ b/tex/texmf-context/tex/context/base/mkiv/typo-tal.lua
@@ -278,7 +278,7 @@ function
characteralign.handler(originalhead,where)
if char then
local font = getfont(current)
-- local unicode = unicodes[font][char]
- local unicode = fontcharacters[font][char].unicode or char
-- ignore tables
+ local unicode = (fontcharacters[font][char] and
fontcharacters[font][char].unicode or char) -- ignore tables
if not unicode then
-- no unicode so forget about it
elseif unicode == separator then

This permits using certain special characters like the Unicode word
joiner as the alignment character in a natural table. Without the patch
ConTeXt aborts with an error:
... typo-tal.lua:281: attempt to index field '?' (a nil value)
Thank you!
Best regards,
Brian
Here is a simple example that aborts without the patch:
\edef\mywordjoiner{\normalUchar"2060}
\starttext
\bTABLE
\setupTABLE[c][1][aligncharacter=yes,alignmentcharacter={\mywordjoiner},align=middle]
