There is not entry for ⊂ in mathfont.properties
I included following line

operator.\u2282.infix = lspace:thickmathspace rspace:thickmathspace

I looked into MathML spec, and it seems that it doesn't define it either.
This is strange, because after all ⊂ is an operator like ∈

Reproducible: Always

> operator.\u2282.infix = lspace:thickmathspace rspace:thickmathspace

Default metadata included to mathfont.properties (on 1.6 trunk).

The following are still missing:
operator.\u228A.infix = lspace:thickmathspace rspace:thickmathspace # ⊊

operator.\u2228.infix = lspace:thickmathspace rspace:thickmathspace # ∨

operator.\u2227.infix = lspace:thickmathspace rspace:thickmathspace # ∧

operator.\u2229.infix = lspace:thickmathspace rspace:thickmathspace # ∩

operator.\u222A.infix = lspace:thickmathspace rspace:thickmathspace # ∪

The patch applies on top of patch from bug 519126

Comment 11

[Frédéric Wang (:fredw)]

The entity names of this bug are already in content/mathml/content/src/mathml.dtd

All MathML entities in attachment 406293 [details] render well. I guess it's not a bug if it's not the case in attachment 406276 [details], because they may not exist in XHTML (I've not checked).

Comment 12

[Frédéric Wang (:fredw)]

I can work on this, now bug 519126 is fixed. I've to check what the W3C specs says about the MathML entities used in XHTML.

The entities not displayed in attachment 406276 [details] are not defined in HTML4 or XHTML*, so it is not a bug. They will probably be defined in (X)HTML5 but this is a separate issue anyway.

subsetneq is actually U+228A (as is subne).

>+operator.\u2227.infix = lspace:4 rspace:4 # ∧
>+operator.\u2228.infix = lspace:4 rspace:4 # ∨

r=karlt on these.

Attachment: Final Patch

2284 => 228A

Comment 17

[Karl Tomlinson (:karlt)]

nsub is U+2284.
subsetneq and subne are U+228A.

We need entries for both U+2284 and U+228A.
