Remarks
This can be used by the verifying application to verify the mapping of the modhex characters.
For all YubiKeys with a firmware version of 2.0 or later, if set in combination with UseAlphaNumericPassword(Boolean), this string will be replaced with a shifted character '1' (typically '!' on most keyboard layouts). This can be used to meet strong password requirements where at least one character is required to be a "special character".
