Your font mrks igrave as a ligature of i + gravecomb, and according to
the SVG fonts spec, ligatures are represented by a sequence of
characters in the "unicode" property, which is what FontForge is doing:

SVG fonts a very dumb font format, if you want to build fonts with
complex substitutions you shouldn't be using SVG fonts.
