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?
