/**
 * Formats simple patterns like "{1} was born in {0}".
 * Minimal subset of MessageFormat; fast, simple, minimal dependencies.
 * Supports only numbered arguments with no type nor style parameters,
 * and formats only string values.
 * Quoting via ASCII apostrophe compatible with ICU MessageFormat default behavior.
 *
 * Factory methods set error codes for syntax errors
 * and for too few or too many arguments/placeholders.
 *
 * SimpleFormatter objects are thread-safe except for assignment and applying new patterns.
 *
 * Example:
 * <pre>
