I have a method which turns any Latin text (e.g. English, French, German, Polish) into its slug form,
e.g. Alpha Bravo Charlie => alpha-bravo-charlie
But it can't work for Cyrillic text (e.g. Russian), so what I'm wanting to do is transliterate the Cyrillic text to Latin characters, then slugify that.
Does anyone have a way to do such transliteration? Whether by actual source or a library.
I'm coding in C#, so a .NET library will work. Alternatively, if you have non-C# code, I'm sure I could convert it.
You can use .NET open source dll library UnidecodeSharpFork to transliterate Cyrillic and many more languages to Latin.
Example usage:
Assert.AreEqual("Rabota s kirillitsey", "Работа с кириллицей".Unidecode());
Assert.AreEqual("CZSczs", "ČŽŠčžš".Unidecode());
Assert.AreEqual("Hello, World!", "Hello, World!".Unidecode());
Testing Cyrillic:
/// <summary>
/// According to http://en.wikipedia.org/wiki/Romanization_of_Russian BGN/PCGN.
/// http://en.wikipedia.org/wiki/BGN/PCGN_romanization_of_Russian
/// With converting "ё" to "yo".
/// </summary>
[TestMethod]
public void RussianAlphabetTest()
{
string russianAlphabetLowercase = "а б в г д е ё ж з и й к л м н о п р с т у ф х ц ч ш щ ъ ы ь э ю я";
string russianAlphabetUppercase = "А Б В Г Д Е Ё Ж З И Й К Л М Н О П Р С Т У Ф Х Ц Ч Ш Щ Ъ Ы Ь Э Ю Я";
string expectedLowercase = "a b v g d e yo zh z i y k l m n o p r s t u f kh ts ch sh shch \" y ' e yu ya";
string expectedUppercase = "A B V G D E Yo Zh Z I Y K L M N O P R S T U F Kh Ts Ch Sh Shch \" Y ' E Yu Ya";
Assert.AreEqual(expectedLowercase, russianAlphabetLowercase.Unidecode());
Assert.AreEqual(expectedUppercase, russianAlphabetUppercase.Unidecode());
}
Simple, fast and powerful. And it's easy to extend/modify transliteration table if you want to.
public static string Translit(string str)
{
string[] lat_up = {"A", "B", "V", "G", "D", "E", "Yo", "Zh", "Z", "I", "Y", "K", "L", "M", "N", "O", "P", "R", "S", "T", "U", "F", "Kh", "Ts", "Ch", "Sh", "Shch", "\"", "Y", "'", "E", "Yu", "Ya"};
string[] lat_low = {"a", "b", "v", "g", "d", "e", "yo", "zh", "z", "i", "y", "k", "l", "m", "n", "o", "p", "r", "s", "t", "u", "f", "kh", "ts", "ch", "sh", "shch", "\"", "y", "'", "e", "yu", "ya"};
string[] rus_up = {"А", "Б", "В", "Г", "Д", "Е", "Ё", "Ж", "З", "И", "Й", "К", "Л", "М", "Н", "О", "П", "Р", "С", "Т", "У", "Ф", "Х", "Ц", "Ч", "Ш", "Щ", "Ъ", "Ы", "Ь", "Э", "Ю", "Я"};
string[] rus_low = { "а", "б", "в", "г", "д", "е", "ё", "ж", "з", "и", "й", "к", "л", "м", "н", "о", "п", "р", "с", "т", "у", "ф", "х", "ц", "ч", "ш", "щ", "ъ", "ы", "ь", "э", "ю", "я"};
for (int i = 0; i <= 32; i++)
{
str = str.Replace(rus_up[i],lat_up[i]);
str = str.Replace(rus_low[i],lat_low[i]);
}
return str;
}
Why can't you just take a transliteration table and make a small regex or subroutine?
Microsoft has a transliteration tool which includes a DLL you could hook into (you would need to check licensing restrictions if you're going to use it non-personally). You can read more about it in Dejan Vesić's blog post
Check this code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace Transliter
{
public partial class Form1 : Form
{
Dictionary<string, string> words = new Dictionary<string, string>();
public Form1()
{
InitializeComponent();
words.Add("а", "a");
words.Add("б", "b");
words.Add("в", "v");
words.Add("г", "g");
words.Add("д", "d");
words.Add("е", "e");
words.Add("ё", "yo");
words.Add("ж", "zh");
words.Add("з", "z");
words.Add("и", "i");
words.Add("й", "j");
words.Add("к", "k");
words.Add("л", "l");
words.Add("м", "m");
words.Add("н", "n");
words.Add("о", "o");
words.Add("п", "p");

private void button1_Click(object sender, EventArgs e)

string source = textBox1.Text;
foreach (KeyValuePair<string, string> pair in words)
{

}
textBox2.Text = source;

}
cryllic to latin:
text.Replace(pair.Key, pair.Value);
latin to cryllic
source.Replace(pair.Value,pair.Key);

Windows 7+ can do this with its Extended Linguistic Services. (You'll need the Windows API Code Pack to do it from .NET)
You can use my library for transliteration: https://github.com/nick-buhro/Translit
It is also available on NuGet.
Example:
var latin = Transliteration.CyrillicToLatin(
"Предками данная мудрость народная!",
Language.Russian);
Console.WriteLine(latin);
// Output: Predkami dannaya mudrost` narodnaya!
Optimized the answer of Sarvar Nishonboev, seems like a simplest solution without unnecessary complexity related to the re-creating of string at each iteration:
public static class Converter
{
private static readonly Dictionary<char, string> ConvertedLetters = new Dictionary<char, string>
{
{'а', "a"},
{'б', "b"},
{'в', "v"},
{'г', "g"},
{'д', "d"},
{'е', "e"},
{'ё', "yo"},
{'ж', "zh"},
{'з', "z"},
{'и', "i"},
{'й', "j"},
{'к', "k"},
{'л', "l"},
{'м', "m"},
{'н', "n"},
{'о', "o"},
{'п', "p"},
{'р', "r"},
{'с', "s"},
{'т', "t"},
{'у', "u"},
{'ф', "f"},
{'х', "h"},
{'ц', "c"},
{'ч', "ch"},
{'ш', "sh"},
{'щ', "sch"},
{'ъ', "j"},
{'ы', "i"},
{'ь', "j"},
{'э', "e"},
{'ю', "yu"},
{'я', "ya"},
{'А', "A"},
{'Б', "B"},
{'В', "V"},
{'Г', "G"},
{'Д', "D"},
{'Е', "E"},
{'Ё', "Yo"},
{'Ж', "Zh"},
{'З', "Z"},
{'И', "I"},
{'Й', "J"},
{'К', "K"},
{'Л', "L"},
{'М', "M"},
{'Н', "N"},
{'О', "O"},
{'П', "P"},
{'Р', "R"},
{'С', "S"},
{'Т', "T"},
{'У', "U"},
{'Ф', "F"},
{'Х', "H"},
{'Ц', "C"},
{'Ч', "Ch"},
{'Ш', "Sh"},
{'Щ', "Sch"},
{'Ъ', "J"},
{'Ы', "I"},
{'Ь', "J"},
{'Э', "E"},
{'Ю', "Yu"},
{'Я', "Ya"}
};
public static string ConvertToLatin(string source)
{
var result = new StringBuilder();
foreach (var letter in source)
{
result.Append(ConvertedLetters[letter]);
}
return result.ToString();
}
}
Use it like this:
Converter.ConvertToLatin("Проверочный текст");

Use this method Just pass your Cyrillic word contain string and this method return Latin English string corresponding to Cyrillic string.
public static string GetLatinCodeFromCyrillic(string str)
{
str = str.Replace("б", "b");
str = str.Replace("Б", "B");
str = str.Replace("в", "v");

str = str.Replace("г", "h");

str = str.Replace("Ґ", "G");
str = str.Replace("д", "d");
str = str.Replace("Д", "D");
str = str.Replace("є", "ye");
str = str.Replace("Э", "Ye");
str = str.Replace("ж", "zh");
str = str.Replace("Ж", "Zh");
