Transliteration in Powershell. How to make multiple choices?

Question

PowerShell

There is a transliteration script available.

function global:TranslitToLAT
{
param([string]$inString)
$Translit_To_LAT = @{
[char]'а' = "a"
[char]'А' = "a"
[char]'б' = "b"
[char]'Б' = "b"
[char]'в' = "v"
[char]'В' = "v"

[char]'З' = "z"
[char]'и' = "i"
[char]'И' = "i"

}
$outChars=""
foreach ($c in $inChars = $inString.ToCharArray())
{
if ($Translit_To_LAT[$c] -cne $Null )
{$outChars += $Translit_To_LAT[$c]}
else
{$outChars += $c}
}
Write-Output $outChars
}

$text = Read-Host "Введите текст"
$log = TranslitToLAT $text
$log

Tell me how you can add several transliteration options for characters?
As an example, if the letter 'I' comes after 'b' and 'b' then it should be spelled "YI", not "I"

Answer 1

I have the following function in my script:

function Convert2Latin($inString) {

# Обрезаем пустые пробелы по краям
$inString = $inString.Trim()


# Определяем таблицу соответствия
$char_ru="а","А","б","Б","в","В","г","Г","д","Д","е","Е","ё","Ё","ж", "Ж", "з","З","и","И","й","Й", "к","К","л","Л","м","М","н","Н","о","О","п","П","р","Р","с","С","т","Т","у","У","ф","Ф","х", "Х", "ц", "Ц", "ч", "Ч", "ш", "Ш", "щ",  "Щ","ъ","Ъ","ы","Ы","ь","Ь","э","Э","ю", "Ю", "я", "Я"
$char_en="a","A","b","B","v","V","g","G","d","D","e","E","e","E","zh","Zh","z","Z","i","I","y","Iy","k","K","l","L","m","M","n","N","o","O","p","P","r","R","s","S","t","T","u","U","f","F","kh","Kh","ts","Ts","ch","Ch","sh","Sh","sch","Sch","","","y","Y","","",  "e","E","yu","Yu","ya","Ya"
$TempString = ""


# Перебираем слово по буквам
for ($i = 0; $i -lt $inString.Length; $i++)
{ 
$t = -1

# Выясняем позицию заменямой буквы в массиве
 Do {$t = $t+1}
    Until (($inString[$i] -ceq $char_ru[$t]) -or ($t -eq 100))

# Дополняем строку конвертированного одновременно производя замену русской буквы на английскую
$TempString = $TempString + ($inString[$i] -creplace $char_ru[$t], $char_en[$t])
}

return $TempString
}

Answer 2

If you do not teach the program how to respond to specific conditions, then nothing. Accordingly, first parse the string and check the sequences (only describe them in the code).

Answer 3

At the beginning of the array are multi-letter combinations:

Answer 4

And could you tell me how to integrate them into the script? In my case, it turns out that in any case, the translation of "yi" is translated into "i", and not "yi"
