SUPPORT: Fixing Missing Icons

Frontiers uses extended Unicode symbols to represent Attributes, Derivatives, and system elements.

Examples include:

❖ ᯽ ꩜ 𖤓 ✶ ✦ ✧ » ✙ ⴵ ⚡︎ ⛃ ⛊ 𖢻 𖣠 ∞
ꉂ ⏾ 𝗓ᶻ

Some operating systems — especially default Windows installations — may not include fonts that support these extended glyph ranges.

If icons appear as: - □ empty boxes - ? question marks - blank spaces - inconsistent rendering across devices

This is a font support issue.

It is not a problem with the Frontiers documents themselves.

 

Why This Happens

Frontiers uses characters from:

  • Extended symbol blocks
  • Supplementary Multilingual Plane (SMP)
  • Rare language glyph ranges

Many default Windows font installations do not fully support these blocks.

Browsers fall back to system fonts.
If the system does not have a compatible font installed, the glyph cannot render.

 

Install the following free fonts from Google:

  • Noto Sans
  • Noto Sans Symbols
  • Noto Sans Symbols 2
  • Noto Emoji (optional but recommended)

Use this installation link: https://fonts.google.com/share?selection.family=Noto+Emoji:wght@300..700|Noto+Sans+Symbols+2|Noto+Sans+Symbols:wght@100..900|Noto+Sans:ital,wght@0,100..900;1,100..900

Installation Steps

  1. Download the font files.
  2. Right-click each .ttf file.
  3. Select Install for All Users.
  4. Restart your browser.
  5. If needed, restart your computer.

 

MacOS & Linux

Most modern macOS and Linux distributions already support these glyph ranges.

If symbols are missing:

  • Install the Noto font families listed above.
  • Refresh your browser.

 

If Issues Persist

  • Ensure your browser is up to date.
  • Clear browser cache.
  • Confirm fonts were installed system-wide (not just per-user).
  • Try a different browser to test fallback behavior.

Frontiers intentionally uses symbolic identifiers for clarity and visual scanning.

Installing proper Unicode support ensures full compatibility across all documents and modules.
