\textfraction broken?

\textfraction broken?

Has there been a change to \textfraction?

Try
1\textfraction{1/2}.

I get
1 /1/2
with ConTeXt  ver: 2017.06.30 (and earlier on the wiki)

Adding

\definefontfeature[fraction][frac=yes]
\definehighlight[textfraction][style={\feature[+][fraction]}]

fixes the problem in the sample just sent.

Sorry for the misfire.

This, and the font has to have the corresponding feature present.

Thanks, Henri.

The mwe seems to work without specifying the font, but that may just be a
deceptive triumph of bad form.

I have a number of fonts in my document in which I would like \textfraction
to work. Is there are global way to prepare them or must I do it one by one?

You cannot prepare the font for this by yourself (unless you are a font designer).  The font needs
to have the "frac" feature present.  Your macro \textfraction{1/2} simply typesets 1/2 with the frac
feature enabled.  You can find out if your font has this feature using the tool otfinfo, e.g.

$ otfinfo -f FiraSans-Regular.otf
aalt	Access All Alternates
c2sc	Small Capitals From Capitals
calt	Contextual Alternates
case	Case-Sensitive Forms
ccmp	Glyph Composition/Decomposition
cpsp	Capital Spacing
dlig	Discretionary Ligatures
dnom	Denominators
frac	Fractions
kern	Kerning
liga	Standard Ligatures
lnum	Lining Figures
mark	Mark Positioning
mgrk	Mathematical Greek
mkmk	Mark to Mark Positioning
numr	Numerators
onum	Oldstyle Figures
ordn	Ordinals
pnum	Proportional Figures
salt	Stylistic Alternates
smcp	Small Capitals
ss01	Stylistic Set 1
ss02	Stylistic Set 2
ss03	Stylistic Set 3
ss04	Stylistic Set 4
subs	Subscript
sups	Superscript
tnum	Tabular Figures
zero	Slashed Zero
