/**
 * An implementation-specific parameter class suitable for initializing {@link
 * ArrayBasedCharEscaper} or {@link ArrayBasedUnicodeEscaper} instances. This class should be used

 * <p>
 * <strong>Thread-Safety:</strong> This class is <strong>NOT thread-safe</strong>.
 * It extends {@link LinkedHashMap} without synchronization. If multiple threads access
 * an instance concurrently, and at least one thread modifies the map structurally,
 * it must be synchronized externally.

 * For thread-safe usage, wrap with {@link java.util.Collections#synchronizedMap(Map)}:
