Regex Editor & Tester

This multiline PCRE pattern matches financial transfer record lines (이체일, Korean for 'transfer date') that start with exactly 10 alphanumeric characters, contain the literal marker 'CTL', and include an 8-digit date beginning with 2 (e.g., 20240115). It then requires an STX control character (\x02), captures two digits into a group, and ends with an SOH control character (\x01) followed by a space. It is typically used to parse legacy banking/wire-transfer message streams with control-character-delimited fields and extract a two-digit day or code value.
