The pattern is constructed as a series of alternations (|) for each unique item, carefully escaping special regex characters to match them literally. For the cryptocurrency addresses, we match them exactly. For regex patterns, we escape all the backslashes and special characters. For data URIs, we match the specific prefixes and content. For LaTeX equations, we escape all special characters including backslashes and braces. For JSON snippets, we escape quotes and braces. For SQL queries, we match the exact strings. For international emails, we include the Unicode characters directly. Each part is separated by | to create an alternation that matches exactly one of these items.
