Regex Pattern Matcher
Design a system to determine if a given text string matches a specific formatting pattern. The pattern supports two special markers: a single-character wildcard that represents any individual character, and a repetition wildcard that allows the immediately preceding character to appear zero or more times. Your implementation must validate if the pattern matches the entire text string, not just a portion of it.
