Special tool for detecting rarely-used character processing capability of financial information system

The utility model belongs to the technical field of financial information systems, and particularly discloses a special tool for detecting the rarely-used character processing capacity of a financial information system, which comprises a first connecting device, a rarely-used character testing device and a second connecting device, the input end and the output end of the rarely-used character testing device are connected with the input device and the tested system through the first connecting device and the second connecting device respectively. The input device is used for inputting identity information of a to-be-verified rarely-used character user, and the input device can generate Chinese characters outside a U + 4E00-U + 9FA5 coding interval; and the tested system performs testing according to the to-be-verified rarely-used character information. The input device can generate Chinese characters beyond the coding interval of U + 4E00-U + 9FA5, the uncommon character range indicated by the JR/T 0253-2022'f
