umlaut doesn't work on o in title

[Karim Haddad]

Hello,

Sorry if this was already reported. But it seems that the umlaut on the o
(two dots on the letter o) doesn't display correctly in the title and
subtitle section of the header. This used to work on the 2.13 and 2.12
versions but not anymore under the stable 2.14.
