Font Awesome飞机类图标显示异常求助：图标显示为方块

Hey there! I’ve run into this exact headache before with Font Awesome icons showing up as blank squares—let’s walk through the most likely fixes for your telegram-plane icon issue:

1. Make Sure You’re Loading the Correct Font Awesome Family #

Most plane-related icons (including telegram-plane) belong to the Brands font family, not the default Solid/Regular families. If you only included the core Font Awesome files, you might be missing the Brands font entirely:

• If you’re using local font files: Double-check your assets/fonts folder includes FontAwesome5Brands.otf (or the corresponding file for your Font Awesome version).
• If you’re using a dependency library (like for Android): Ensure you’ve added the Brands dependency alongside the core one. For example, in Gradle:

  implementation 'com.github.joanzapata.iconify:android-iconify-fontawesome:2.2.2'
  implementation 'com.github.joanzapata.iconify:android-iconify-fontawesome-brands:2.2.2'
  

2. Verify the Icon’s Unicode and Version Match #

Your string  is correct for fa-telegram-plane, but only if you’re using Font Awesome 5 (this icon was added in v5.0.0). If you’re on an older version, this Unicode won’t exist—double-check your Font Awesome version aligns with the icon’s release version.

3. Ensure the Correct Typeface is Applied to Your View #

Even if you have the font file, you need to tell your TextView/View to use the Brands typeface:

• In code (Android example):

  Typeface brandsTypeface = Typeface.createFromAsset(getAssets(), "fonts/FontAwesome5Brands.otf");
  yourTextView.setTypeface(brandsTypeface);
  

• In XML (using a custom font family):
  Create a font resource file pointing to the Brands font, then set android:fontFamily="@font/font_awesome_brands" on your TextView.

4. Check for Encoding or String Format Issues #

Make sure your strings.xml file is saved in UTF-8 encoding—sometimes incorrect encoding can mangle Unicode characters. Also, double-check that your string doesn’t have typos (like missing the semicolon at the end of ).

5. Rule Out Font Conflicts #

If your app has a global theme that sets a default font family, it might be overriding the Font Awesome typeface. Try explicitly setting the Font Awesome Brands typeface on your target view to bypass any global settings.

Start with checking the Brands font inclusion—that’s the #1 culprit for missing brand-specific icons like telegram-plane!
