 * TRANSLATORS: This format string belongs to the macro used for
 * printing the "Label: Value Unit" lines on the details tab, e.g.
 * "Temperature: 10 °C" or "Latitude: 95.7°".
 * The %s stand for:
 *   - label
 *   - ": " if label is not empty, else empty
 *   - value
 *   - space if unit is not degree "°" (but this is not °C or °F!)
 *   - unit
 * Usually, you should leave this unchanged, BUT...
 * RTL TRANSLATORS: In case you did not translate the measurement
 * unit, use LRM (left-to-right mark) etc. to align it properly with
 * its numeric value.
