I am a big shot, and my ID card information code is E863. In the mobile phone system, the font needs to be set to a certain font before it can be displayed. Otherwise, it is generally displayed as a question mark, a space and a box cross. Except for a few departments such as the Ministry of Public Security, which can find two codes in the system font, the system fonts of other departments can only recognize one code, which brings a lot of trouble to our daily life. For example, when applying for a social security card, social security information and identity information cannot match. The health code cannot be used because real-name authentication does not support two codes. When vaccinated, the information system could not recognize the word. Xue Xin. The academic information of com can't display this word normally. You can't enter this word in medical insurance information, and so on. Rare characters also belong to the category of Chinese characters. We can't be prevented from doing things just because our parents give us names with uncommon words and there will be some trouble in doing things. I hope the relevant departments can attach importance to this issue and protect our rights and interests.
