1st Alternative(\{(?:[^{}]++|(?1))*})(*SKIP)(*F)

Group 1(\{(?:[^{}]++|(?1))*})

\{the literal { (123₁₀ / 173₈ / 7B₁₆)

Non-Capturing Group(?:[^{}]++|(?1))*

*repeats the group contents below any number of times:

1st Alternative[^{}]++

Negated Character Class[^{}]++

++matches at least one character outside the set below:

{the literal { (123₁₀ / 173₈ / 7B₁₆)

}the literal } (125₁₀ / 175₈ / 7D₁₆)

2nd Alternative(?1)

(?1)calls group 1 as a subroutine

}the literal } (125₁₀ / 175₈ / 7D₁₆)

(*SKIP)acts like (*PRUNE), but the next unanchored match attempt starts where (*SKIP) was reached instead of at the next subject character

(*F)forces the current match attempt to fail at this position

2nd Alternative\|

\|the literal | (124₁₀ / 174₈ / 7C₁₆)

Global pattern flags

g modifier: global. Finds all matches instead of stopping after the first

m modifier: multiline. Causes ^ and $ to match the start and end of each line, not only the start and end of the string
