Determine the number of characters which are allowed in a field?

Hope this helps Unfortunately this is not possible, I think. From the given length in bytes you can only calculate a maximum number of characters which would fit into this field.
For unicode ABAP systems we know that SAP stores the character data in code pages 4102 / 4103 which is UTF-16 (big and little endian format). That means a character needs at least 2 bytes, i.e. the maximum length can be calculated as uc_length / 2 = 40 chars in your example. I don't think that SAP already uses any 4-byte character yet. However, this would be possible with code pages 4102 / 4103. Therefore it depends on which Unicode character you will put in the field, it might be that less than 40 characters could be stored in a field with uc_length=80.

fixed the issue. Will look into that further Well, according to the documentation, the notes field is the same as a field with the type set to note. That is equivalent to the nText field in SQL Server. Here is the limit for that field from the docs:

hope this fix your issue I have a PDF document with a number of text fields, several of which have a maximum length - namely, a maximum number of allowable characters. , I think you're looking for something like this:
code :
    Dim reader As New PdfReader("YourPdf.pdf")
    Dim fields As IDictionary(Of String, iTextSharp.text.pdf.AcroFields.Item) = reader.AcroFields.Fields
    For Each key As String In fields.Keys
        Dim fieldItem = reader.AcroFields.GetFieldItem(key)
        Dim pdfDictionary As PdfDictionary = fieldItem.GetWidget(0)

        Dim pdfFieldName As String = key
        Dim maxFieldLength As Integer = Int32.Parse(pdfDictionary.GetAsNumber(PdfName.MAXLEN).ToString())

        Console.WriteLine("Field={0}, MaxLen={1}", pdfFieldName, maxFieldLength.ToString())
    Next

You can use any (UTF8) character in the field name which aren't special (contains ".", or starts with "$").
