More information: I have: Mozilla Firefox 38.0 Web page that displays this behaviour: https://github.com/cbm755/sympy/commit/cad689d3b82aa332a55b601d1a004f26fa6108f6 , search for "assert upretty( Symbol('Fhat') ) == u('F" (without the quotes) and the problem is directly after that. CSS-requested font list: Consolas,"Liberation Mono",Menlo,Courier,monospace Used font: Liberation Mono is used
Interestingly, the combining character is immediately followed by a span: <span class="pl-s"><span class="pl-pds">'</span>F̂<span class="pl-pds">'</span></span> Wild guess: the span right after Unicode COMBINING HAT disrupts Mozilla's rendering engine in some way. (It would explain why the issue is hard to reproduce.) Detail: The pl-pds span changes font color, to a color of the same value; i.e. this may or may not contribute to the situation. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/51554 Title: Unicode combining characters don't combine properly.
