It's very hard to understand what you're asking. You want to match a string like "[BT:CHROME, BV:55, BL:en, CC:CZ]" and include the square brackets in the resulting field?

Then perhaps `(?<name-of-field>\[[^\]]*\])` would do. It should match a `[` followed by zero or more characters of any kind except `]`, followed by `]`.
