Bug#989882: fonts-dejavu-extra: Wrong glyph for 25EF LARGE CIRCLE in DejaVu Math TeXGyre
Package: fonts-dejavu-extra
Version: 2.37-1
Severity: normal
Dear Maintainer,
The glyph for Character '◯' (9711, 0x25EF) LARGE CIRCLE in the
DejaVu Math TeXGyre otf font shows a large *black* circle.
From the sample glyph and comparing with other fonts, I expect a *white*
circle (black large circle is 0x25CB).
As a result, the following page displays two large *black* circles in
Firefox with the default font setting (DejaVu):
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"; xml:lang="en" lang="en">
<head>
<meta charset="utf-8"/>
<meta name="viewport" content="width=device-width, initial-scale=1" />
</head>
<body>
<main>
<math xmlns="http://www.w3.org/1998/Math/MathML"; display="block">
<mo>◯</mo> <mo>◯</mo>
</math>
</main>
</body>
</html>
A wrong symbol for the "circle operator" is a nontrivial problem for the use
of MathML with Firefox.
I checked with the latest version of the font on CTAN
(https://www.ctan.org/pkg/tex-gyre-math-dejavu) and still found the wrong
glyph.
Sincerely
Günter Milde
