How to generate superscript and subscript glyphs
There are 3 steps
=============================================================================
Step 1: Add Glyphs
-----------------------------------------------------------------------------
If these glyphs already exist, you can skip this step.
a=a.sups
b=b.sups
c=c.sups
d=d.sups
e=e.sups
f=f.sups
g=g.sups
h=h.sups
i=i.sups
j=j.sups
k=k.sups
l=l.sups
m=m.sups
n=n.sups
o=o.sups
p=p.sups
q=q.sups
r=r.sups
s=s.sups
t=t.sups
u=u.sups
v=v.sups
w=w.sups
x=x.sups
y=y.sups
z=z.sups
zero=zero.sups
one=one.sups
two=two.sups
three=three.sups
four=four.sups
five=five.sups
six=six.sups
seven=seven.sups
eight=eight.sups
nine=nine.sups
parenleft=parenleft.sups
parenright=parenright.sups
plus=plus.sups
minus=minus.sups
equal=equal.sups
=============================================================================
Step 2: Generate & transform with RMX Scaler
-----------------------------------------------------------------------------
Make sure "Scale Sidebearings" is enabled in RMX Scaler.
Note that a-z(), 0-9 and +-= are scaled separately.
Start in the "Font" view in Glyphs (the tab with an overview of all glyphs)
and multiselect each set (e.g. "a-z()") then invoke the RMX Scaler.
-----------------------------------------------------------------------------
a-z, "(" and ")"
{
"width" : [
66.6,
66.6,
66.6,
66.6,
66.6,
66.6
],
"weight" : [
0,
0,
-50,
-50,
-300,
-300
],
"height" : [
66.6,
66.6,
66.6,
66.6,
66.6,
66.6
],
"verticalShift" : [
1024,
1024,
1024,
1024,
1024,
1024
]
}
-----------------------------------------------------------------------------
0-9
{
"width" : [
66.6,
66.6,
66.6,
66.6,
66.6,
66.6
],
"weight" : [
0,

-50,
-50,
-300,
-300
],
"height" : [
60,

],
"verticalShift" : [
1024,
1024,
1024,
1024,
1024,
1024
]
}
-----------------------------------------------------------------------------
"+", "-" and "="
{
"width" : [
66.6,
66.6,
66.6,
66.6,
66.6,
66.6
],
"weight" : [
0,

-50,

-300,
-300
],
"height" : [
63,

],
"verticalShift" : [
1024,
1024,
1024,
1024,
1024,
1024
]
}
=============================================================================
Step 3: Adjust X offset for slanted glyphs
-----------------------------------------------------------------------------
For each slanted master:
1. Select all .subs glyphs
2. Open Filter > Transformations
3. Set Translate X = 126 (and all other values to neutral)
4. Apply
