5) Do not translate anchor fragments in links (the part after «#»), as they must remain the same to work correctly.

5.1) If an existing translation has a link with an anchor fragment different to the anchor fragment in the English source, then this is an error. Fix this by using the anchor fragment of the English source.

Example:

        UnicodeString unicodeStringChinese = new UnicodeString(unicodeChars, false);
        assertEquals(unicodeChars, unicodeStringChinese.toString(), "toString should handle unicode characters correctly");

        // Test toString with buffer containing only zero (should result in empty string)
        rpc.unicode_string zeroBufferRus = new rpc.unicode_string();
        zeroBufferRus.buffer = new short[] { 0 };

   * #descendingMultiset()} will not reflect any changes you make to the behavior of methods such as
   * {@link #add(Object)} or {@link #pollFirstEntry}. This skeleton implementation correctly
   * delegates each of its operations to the appropriate methods of this {@code
   * ForwardingSortedMultiset}.
   *
   * <p>In many cases, you may wish to override {@link #descendingMultiset()} to return an instance

6.  For the mainline flavor, we test the libraries using OpenJDK 8, 11, and 17
    on Linux, with some additional testing on newer JDKs and on Windows. Some
    features, especially in `com.google.common.io`, may not work correctly in
    non-Linux environments. For the Android flavor, our unit tests also run on
    API level 23 (Marshmallow).
