replace NETWORK_ICON

The original icon (U+FBF1) is in fact a ligature. Some terminals do
funky things when displaying it. For example:

    print '\uFBF1 42 abc'

When executed in a VTE-based terminal with Nerd Fonts, it'll print this:

    42 X abc

Here X stands for the glyph that Nerd Fonts uses for U+FBF1.
