The pipe character has a special meaning in batch commands, so it must be escaped using the caret character. This should work:

DECLARE @Text AS VARCHAR(100)
DECLARE @Cmd AS VARCHAR(100)
SET @Text = 'Hello world^| '
SET @Cmd ='echo ' +  @Text + ' > C:\AppTextFile.txt'
EXECUTE Master.dbo.xp_CmdShell  @Cmd

Although this is really not a good way to write data to a text file: usually SQL Server should not have permission to write to the root of the C: drive, and xp_cmdshell is disabled by default. I suggest you look at alternatives like sqlcmd.exe, bcp.exe or a small script in your preferred language (PowerShell, Perl, Python, whatever).

It is generally much easier, safer and more flexible to query data from SQL Server than it is to push it out from the server side. In your specific case, it looks like you want to write out a delimited file, and bcp.exe is intended for that purpose.

Other way to do this

DECLARE @File  varchar(300) = 'c:\Temp\out.txt'
DECLARE @Text  varchar(8000) = 'Sample text'
DECLARE @OLE            INT 
DECLARE @FileID         INT

EXECUTE sp_OACreate 'Scripting.FileSystemObject', @OLE OUT 
EXECUTE sp_OAMethod @OLE, 'OpenTextFile', @FileID OUT, @File, 8, 1 
EXECUTE sp_OAMethod @FileID, 'WriteLine', Null, @Text
EXECUTE sp_OADestroy @FileID 
EXECUTE sp_OADestroy @OLE 

Check for errors using SP result

EXECUTE @result = sp_OAMethod @OLE, 'OpenTextFile', @FileID OUT, @File, 8, 1
if @result<>0 GOTO ON_ERROR

Haven't found the way to read error message though

wrap it with two pairs of single quotes,

DECLARE @Text AS VARCHAR(100)
DECLARE @Cmd AS VARCHAR(100)
SET @Text = '''Hello world| '''
SET @Cmd ='echo ' +  @Text + ' > C:\AppTextFile.txt'
EXECUTE Master.dbo.xp_CmdShell  @Cmd
