I took all the commented-out unmapped glyphs from the list above and pored over them. A couple were overlooked:

'f111' => '25cf',  # ● BLACK CIRCLE (icon-circle)
'f10c' => '25cb',  # ○ WHITE CIRCLE (icon-circle-blank)

# NOTE: REQUIRES CHANGING icon-refresh TO 🗘 U+1F5D8 CLOCKWISE RIGHT AND LEFT SEMICIRCLE ARROWS
'f079' => '1f501',  # 🔁 CLOCKWISE RIGHTWARDS AND LEFTWARDS OPEN CIRCLE ARROWS (icon-retweet)

Many of them can be encoded, with a caveat: they aren't actually in a release of Unicode yet. But they're in the pipeline as imports from Wingdings, approved, and pending publication. There's a list here, and the current Symbola encodes all of them (or at least the ones I use below).

'f008' => '1f39e',  # 🎞 FILM (icon-film)
'f014' => '1f5d1',  # 🗑 WASTEBASKET (icon-trash)
'f03e' => '1f5bb',  # 🖻 DOCUMENT WITH PICTURE (icon-picture)
'f06e' => '1f441',  # 👁 EYE (icon-eye-open)
'f07d' => '2b6d',  # ⭭ UP DOWN TRIANGLE-HEADED ARROW A2 (icon-resize-vertical)
'f07e' => '2b6c',  # ⭬ LEFT RIGHT TRIANGLE-HEADED ARROW A2 (icon-resize-horizontal)
'f0a0' => '1f5b4',  # 🖴 HARD DISK (icon-hdd)
'f0e5' => '1f59e',  # 🖞 RIGHT SPEECH BUBBLE (icon-comment-alt)
'f0e6' => '1f5a3',  # 🖣 TWO SPEECH BUBBLES (icon-comments-alt)

I also have some slightly creative interpretations that nonetheless should get the point across with a fallback font.

Existing Unicode:

'f012' => '1f4f6',  # 📶 ANTENNA WITH BARS (icon-signal)
'f110' => '231b',  # ⌛ HOURGLASS (icon-spinner)

Proposed and accepted but unreleased:

'f02b' => '1f3ff',  # 🏿 PRICE TAG (icon-tag) (no Symbola glyph)
'f0ea' => '1f4cb',  # 📋 CLIPBOARD (icon-paste)
'f0c5' => '1f5e9',  # 🗩 PAGES (icon-copy)
'f053' => '2ba7',  # ⮧ BLACK LEFTWARDS ARROWHEAD 1 (icon-chevron-left)
'f054' => '2ba8',  # ⮨ BLACK RIGHTWARDS ARROWHEAD 1 (icon-chevron-right)
'f077' => '2ba9',  # ⮩ BLACK UPWARDS ARROWHEAD 1 (icon-chevron-up)
'f078' => '2baa',  # ⮪ BLACK DOWNWARDS ARROWHEAD 1 (icon-chevron-down)
'f0b2' => '1f5d6',  # 🗖 MAXIMIZE (icon-fullscreen)
'f018' => '1f3da',  # 🏚 HIGHWAY WITH BILLBOARD (icon-road)
'f0e4' => '1f5c3',  # ok, really stretching it: 🗃 FRAMED PICTURE WITH TILES (icon-dashboard)
'f0fb' => '1f6ca',  # 🛊 SMALL AIRPLANE (icon-fighter-jet)

Other comments:

• icon-briefcase is mapped to 💼 BRIEFCASE, but the icon looks more like the glyph for icon-suitcase.
• icon-comment and icon-comments should possibly be swapped with the alt versions proposed above; FA uses black for the default and white for "alt", but the Unicode glyphs are the other way around.
• There are three major categories of remaining icons not in Unicode: text editing symbols (unlikely to appear in Unicode anytime soon), company logos (perfect for the PUA), and simple white shapes in a black circle or other outline. It bothers me that the latter can't be expressed, but I can't think of anything that doesn't at least require using a combining character. I would love a better idea.
