A .net Standard 2/C# library for working with homoglyphs (characters that look identical or similar but have different unicode values).
Homoglyphic makes it easy to find strings in a body of text which contains homoglyphs to bypass regular string matching. Useful for simplifying spam/phishing detection, content moderation and scrubbing text used for training ML models.
This project was inspired by Homoglyph and the list of homogylphys in this project can be found here
Install-Package Homoglyphic
Homoglyphic consists of two main classes, the HomoglyphicLoader and HomoglyphicSearch.
The HomoglyphicLoader accepts the file path to a CSV file of homoglyphic character sets and returns a list of hashsets representing a set of homoglyphs.
Once you have your list of homoglyphs, you can then use it to create an instance of the HomoglyphSearch class which has a single function: Search. The Search function will accept a string or list of strings and return a SearchResult ojbect for each occurance of a search string found in the string being searched.
var sets = HomoglyphLoader.LoadSets("homoglyphs.csv");
var search = new HomoglyphSearch(sets);
var result = search.Search("Th1s Is A Test", new List<string>() { "This", "Test" });
