When I enter some capital cyrillic letters in PowerShell console, they are not displayed. For instance 'A cyrillic'

When I enter some capital Cyrillic letters in Powershell console, they are not displayed.

Only 9 capital letters I'm able to enter when I declare a variable. When I want to type $a = 'A', only $a = '' appears in console.

This i valid for 21 capital Cyrillic letters. Only 'ТЪУШЩСФХЦ' are able to be written.

The situation in ISE is OK. Everything is OK.

[System.Text.Encoding]::Default, $OutputEncoding, [console]::OutputEncoding in ISE producing equal result

IsSingleByte : True

BodyName : koi8-r

EncodingName : Cyrillic (Windows)

HeaderName : windows-1251

WebName : windows-1251

WindowsCodePage : 1251

IsBrowserDisplay : True

IsBrowserSave : True

IsMailNewsDisplay : True

IsMailNewsSave : True

EncoderFallback : System.Text.InternalEncoderBestFitFallback

DecoderFallback : System.Text.InternalDecoderBestFitFallback

IsReadOnly : True

CodePage : 1251

$PSDefaultParameterValues['*:Encoding'] = [System.Text.Encoding]::Default in console no result.

Perhaps your problem is an incorrect code page? The Windows-1251 character set (https://en.wikipedia.org/wiki/Windows-1251) is different to the Windows KOI8-R character set (https://en.wikipedia.org/wiki/KOI8-R#:~:text=KOI8%20stands%20for%20Kod%20Obmena%20Informatsiey%2C%208%20bit,In%20IBM%2C%20KOI8-R%20is%20assigned%20code%20page%20878.)

One (1251) encodes the capital "A" as 0xC0, and the other (KOI8-R) uses 0xE1.

Thank you for your effort, but if the code page is a problem, why small Cyrillic letters are OK? Probably there is something other.

If it's not a codepage problem, then perhaps it's a font problem?

Check the font used by the ISE. The font is probably a TrueType font. Then check the font used in the PowerShell window. Are the fonts the same?

Thank you for your effort. I think the situation is different. Small Cyrillic are OK. Capital letters 'ТЪУШЩСФХЦ' too. Only the rest 21 capital letters aren't.

If you run this bit of code, are the characters represented correctly?


# UTF8
#               Т        А        Ъ        В        Г        Ԍ        И
[byte[]]$x = 208,162, 208,144, 208,170, 208,146, 208,147, 212,140, 208,152
[System.Text.Encoding]::UTF8.GetString($x)

Or, if you want to use the Unicode code-points:

write-host $([char]0x0418) # И  U+0418
write-host $([char]0x0422) # T  U+0422

Your proposal is for symbols which are OK.

Based on your proposal write-host $([char]0x0411) and it gives 'Б'.

The problem is not displaying capital letters from script. The problem is when I type letter 'Б' from keyboard, it is not displayed on screen and the cursor not moves ahead. This is not the same for letters 'ТЪУШЩСФХЦ'. When I'm typing them, the letters appeared on the screen normally.

Thank you for your effort.

Everything in your proposal is OK.

The problem is when I'm typing the letter 'Б' from keyboard, nothing happens on the screen. When I'm typing letters 'ТЪУШЩСФХЦ' everything is OK.

I'm just trying to home in on where the problem lies. I suspect it's on the input side.

Have you tried this:

[Console]::OutputEncoding = [System.Text.Encoding]::GetEncoding("utf-8")

The output from my PowerShell console ([console]::OutputEncoding) looks like this, and I have no problems entering and displaying the characters that are giving you a problem:

IsSingleByte      : True
BodyName          : IBM437
EncodingName      : OEM United States
HeaderName        : IBM437
WebName           : IBM437
WindowsCodePage   : 1252
IsBrowserDisplay  : False
IsBrowserSave     : False
IsMailNewsDisplay : False
IsMailNewsSave    : False
EncoderFallback   : System.Text.InternalEncoderBestFitFallback
DecoderFallback   : System.Text.InternalDecoderBestFitFallback
IsReadOnly        : True
CodePage          : 437

I tried $OutputEncoding = [Console]::OutputEncoding = [Text.UTF8Encoding]::UTF8

and your proposal [Console]::OutputEncoding = [System.Text.Encoding]::GetEncoding("utf-8"). The result is the same. It's not possible to define $a='Б' from the keyboard. When I paste $a='Б' and after that type $a, the result is 'Б'

PS C:\Users\isgmg> $a='Б'

PS C:\Users\isgmg> $a

Б

Can you further explain what "typing" means? Are you entering the characters from a PowerShell console? Or are you entering the character while running script? Or while entering data into a form?

From a PowerShell console, try running this:

$x = Read-Host "Enter a Capital letter in Cryllic: " "====================`nUTF8" $x|format-hex -encoding UTF8 "`n====================`nUnicode" $x|format-hex -encoding Unicode "`n====================`nCharacter as typed" $x

Do the results differ if you enter the character from the keyboard or by pasting it into the Read-Host?

Can you post the results from this? **Get-Culture | fl *** do that from the ISE and from a Powershell console.

Please look carefully the jpg file attached. On the row before the last on the screen тхере is nothing, but when I copied and pasted the screen content here, there is letter А.

Previously you said that you were using CodePage 1252? I don't see the character "Б" in that code page.

Try using CodePage 65001 instead.

Георги Грозданов 0

The reason is I run

[Console]::OutputEncoding = [System.Text.Encoding]::GetEncoding("utf-8")
I tryed CodePage 65001 without success. Selected Beta:Use UTF8 for worlwide ...
