[Inkscape-translator] probably a bug in degree sign character representation

The degree sign is mostly represented in HTML entity (°) instead of direct Unicode character (0x00B0, i.e. ˚), so in some menus it shows as HTML (for example in Object -> Rotate 90° etc.)

I presume that all occurences should be changed back to Unicode.

Related to this, I am not sure what is the part of the first variable here (and other similar strings): <b>Curve segment</b>: angle %3.2f&#176;, distance % s; etc.
