(2 input bytes 1 output byte)  \nform E0 to EF hex  ==\u003e Substituted by ? (3 input bytes 1 output byte)  \nform F0 to FF hex  ==\u003e Substituted by ?? (4 input bytes 2 output byte)  \n\nExecution example :  \n\nGPClean \u003c Input_File.txt \u003e Output_File.txt  \n\nEj.  \n\n**Input_File.txt**  :  \n\n🙊MICA🙊\n\n**Output_File.txt** : \n\n??MICA??\n\n\n## UTF8 Specification :  \n\nSee here [UTF8 Specification](https://www.fileformat.info/info/unicode/utf8.htm)  \n\nThe value of each individual byte indicates its UTF-8 function, as follows:  \n\n00 to 7F hex (0 to 127): first and only byte of a sequence.  \n80 to BF hex (128 to 191): continuing byte in a multi-byte sequence.  \nC2 to DF hex (194 to 223): first byte of a two-byte sequence.  \nE0 to EF hex (224 to 239): first byte of a three-byte sequence.  \nF0 to FF hex (240 to 255): first byte of a four-byte sequence.  \n\n## Coding With :  \n\nVisual Code Editor   \n\n----  \n\n## Build :  \n\nmake -f GPClean.c    \n\n----  \n\n\n## Authors  \n\n* **Giovanni Palleschi** - [gpalleschi](https://github.com/gpalleschi)  \n\n----  \n\n## Prerequisites :  \n\nN.A.   \n\n## License :  \n\nThis project is licensed under the GNU GENERAL PUBLIC LICENSE 3.0 License - see the [LICENSE](LICENSE) file for details  ","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgpalleschi%2Fgpclean","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgpalleschi%2Fgpclean","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgpalleschi%2Fgpclean/lists"}
