A laptop showing OpenHistoricalMap showing Spain in 1925, held up in front of a sign with the Unicode logo, followed by: time zone conversion, alphabetical sorting, metric versus imperial, scientific notation. Bidirectional text (spelled backwards). Currency exchange, calendar formats, emoji searchability.
It was a privilege to introduce the software #internationalization and #localization community to #OpenHistoricalMap (and #OpenStreetMap and @maplibre.org) at #UTW2025. Join us in mapping yesterday already!
