Spaces replaced with Question Marks

[wardenm]

aspose.words 4.4.3, using the following code but when the .doc gets made some of the spaces are replaced with question marks, particularly a lot of spaces in a row. what causes this?

Dim buffer() As Byte
Dim encoder As New System.Text.ASCIIEncoding
Dim str As String = "AllTextHere"
ReDim buffer(str.Length - 1)
encoder.GetBytes(str, 0, str.Length, buffer, 0)
Dim ms As MemoryStream = New MemoryStream(buffer, False)
Dim license As Aspose.Words.License = New Aspose.Words.License
license.SetLicense(Request.ServerVariables("APPL_PHYSICAL_PATH") + "bin\Aspose.Words.lic")
Dim license2 As Aspose.pdf.License = New Aspose.pdf.License
license2.SetLicense(Request.ServerVariables("APPL_PHYSICAL_PATH") + "bin\Aspose.PDF.lic")
Dim WDoc As Aspose.Words.Document = New Aspose.Words.Document(ms)

Hello!
Thank you for your inquiry.
In the code fragment you are converting a string with HTML document to byte array with its ASCII representation. Ensure your document doesn’t contain characters that cannot be represented in ASCII. In general it’s better to use UTF-8 or any other Unicode encoding.

if i used UTF-8, the question marks turn to capital A’s with carots over them. if i change to unicode encoding, I get an error on the

Dim WDoc As Aspose.Words.Document = New Aspose.Words.Document(ms)

line, the error is
Exception Details: Aspose.Words.UnsupportedFileFormatException: Unknown file format.

Hi
Thanks for your request. Please try using the following code:

Dim buffer() As Byte
Dim str As String = "AllTextHere"
buffer = System.Text.Encoding.UTF8.GetBytes(str)
Dim ms As MemoryStream = New MemoryStream(buffer)
Dim WDoc As Aspose.Words.Document = New Aspose.Words.Document(ms)

Hope this helps.
Best regards.
