A simple matching pattern to convert that follows basic rules:

• • Means match anything, so ca* means match anything starting with ca
• ? Means match single character. So, b?b will match to bob and bab, and so on.
• \ is an escape character. So for example, * means do not treat as a match, but literal character .

To use a \ as a character in the string, it must be escaped. So in the pattern it should be represented by \ to be treated as an ordinary \ character instead of an escape.

An optional flag to indicate if the pattern matching should be treated as case-sensitive or not when comparing By default, it is assumed case sensitive.
