Was your Emacs built with libotf and other libraries mentioned in INSTALL under "Complex Text Layout"? When I arrange for Emacs to use a font that supports both 'o' and the solidus, the sequence you show does display as a single glyph. (My default font doesn't have the solidus, so I need that special arrangement.) The fact that Emacs displays a cursor on both of the characters clearly shows that Emacs did combine them, but the font and/or the shaping engine didn't display them overlaid. Not sure why, perhaps upgrade your libotf and related libraries?
