// accent_permutator is a tool to transform characters to accented characters such as "o" to "ò"
// tool will accept ASCII, UTF-8 and $HEX[] formatted wordlists
// ex input: plaintext "password" or "$HEX[70617373776f7264]"
// ex usage: cat wordlist.txt | ./accent_permutator.bin | hashcat.bin...
// written by cyclone
// changelog
// v2023-08-10.2330; initial github release
// v2023-08-16.1430; changed read logic to process large wordlists line by line, preventing memory issues
