Hmm the import was a long time ago but I think it is (arguably) correct.
> \upAlpha=macro:
->\symup \Alpha .
l.7 \show\upAlpha
?
> \mupAlpha=the character Α.
l.8 \show\mupAlpha
?
from
\documentclass{article}
\usepackage{unicode-math}
\begin{document}
\show\upAlpha
\show\mupAlpha
\end{document}
show unicode-math
defines both (with technically different definitions)
But the other alphabets are all using commands that map directly to the Unicode slot eg
\mbfAlpha=the character 𝚨
so this does seem strange.
The initial inclusion of this set was via some perl (I think) that massaged @wspr's tex file, so the difference is a bit surprising. I wonder if that has changed, I'll see if I can see anything in the logs.
... Ah this changed in unicode-math
in in 2015 (so "recently" compared to the age of this data:-)

greek symbols: \upbeta and \itbeta are defined to be always upright and italic respectively
diff --git a/unicode-math-table.tex b/unicode-math-table.tex
index 5d3f263..acef891 100644
--- a/unicode-math-table.tex
+++ b/unicode-math-table.tex
-\UnicodeMathSymbol{"00391}{\upAlpha }{\mathalpha}{capital alpha, greek}%
....
+\UnicodeMathSymbol{"00391}{\mupAlpha }{\mathalpha}{capital alpha, greek}%
So... On the face of it I'm not against the proposal to re-sync with the unicode-math
table Let me check and report back.
rather than going through all the re-assembling of the corresponding TeX, W3C etc. source files -- which is apparently what was done here).
yes well in some cases it was a bit easier for me as the direction was reversed, unicode.xml
is the source of the mathml operator dictionary, the mathml and html entity list etc,, but tracking every unicode release since 1999 or so has proved interesting at times:-)
Actually the import code is more or less still in this repository in xslt
<xsl:variable name="umt">
<umd>
<xsl:for-each select="tokenize(unparsed-text('https://raw.githubusercontent.com/wspr/unicode-math/master/unicode-math-table.tex'),
'[ ]+')[contains(.,'UnicodeMathSymbol')]">
<xsl:variable name="id" select="replace(.,'.UnicodeMathSymbol\{"([0-9A-F]+)\}.*','$1')"/>
<character id="U{if(string-length($id)=4) then '0' else ''}{$id}">
<xsl:value-of select="replace(.,'.UnicodeMathSymbol\{"([0-9A-F]+)\}\{(\\[^{} ]+).*','$2')"/>
</character>
</xsl:for-each>
</umd>
</xsl:variable>
I'll adjust to run on a current copy of unicode-math
and see how much changes....
@Omikhleia I just updated the script to use the current unicode-math repo and it would make the following diff
I'll probably update unicode-math
later but want to think about it first, but is this closer to what you expected?

Thanks a lot for the quick reply!
but is this closer to what you expected?
Yes, it does sound logical to me.
Besides my original concern, I just notice the duplicates now, such as \lbrbrak
(on both U02772 and U03014 in the original unicode.xml
) -- It would now be left on U02772 only, as in the latest/current unicode-math (which doesn't map U03014 at all).
Likewise on the mbfsansepsilon / mbfsansvarepsilon (etc.) change revealed from your diff -- If I checked correctly, these characters were visibly inverted -- vs. the "original" TeX definition \epsilon
(lunate) and \varepsilon
(uncial) --, so the change here seems logical too, in line with the expectations.
I don't know how stable are those unicode-math mappings now, however -- and whether people actually use all these "direct" commands in real life.
But I'm real glad this unicode.xml
exists, as a way for SILE to extract from one source both the TeX-like symbol (for that syntax) and the operator default properties (stretchy, largeop etc.) for its MathML engine ^^

The U+3014 is CJK punctuation which got deprecated for math use after the big STIX math update (Unicode 3.2) the current public version with the same \lbrbrak name pointing at both slots is clearly an error. So this update will fix more than planned...

They probably don't get used much as betweeen using \mathsf{\epsilon} and the direct use of the character, there isn't a lot of call to use the individual command versions but they do form a useful reference point and anyway if I list them in the file they should at least be correct.

thanks, that's the idea
Message ID: @.***>
Greetings,
The unicode-math LaTeX package table has greek characters (U+00391 and subsequent) as
\mupAlpha
etc.However, the Unicode XML file in this repository has them as
<mathlatex set="unicode-math">\upAlpha</mathlatex>
etc. with the initial "m" dropped (whereas other mappings seem correct at a glance[^1])Could this be a weird conversion/import artifact?
Thanks in advance for any feedback! (For the context behind my question: I'm considering using this "aggregated"
unicode.xml
file to generate some extended tables (MathML operator dictionary, LaTeX-like aliases, etc.) for the SILE typesetting system, rather than going through all the re-assembling of the corresponding TeX, W3C etc. source files -- which is apparently what was done here).[^1]: For instance
\mitAlpha
(U1D6E2) etc. have the expected names.
