Pound Sign vs. GBP
`£` is the familiar pound sign used in currency formatting, while GBP is the ISO 4217 code for pound sterling. The code is especially useful in international, financial, or machine-readable contexts where explicit identification matters.
Use `£` where the currency is already clear; use `GBP` when pound sterling needs an explicit ISO currency identifier.

Important caveats
Usage Boundary
