当iTextSharp读入时，PDF名称正在缩写

Question

我正在尝试使用iTextSharp阅读PDF文档。阅读该文件，但不知何故，我注意到该名称是缩写。例如。如果名称是“采购定义文档”，则将名称缩写为“Proc def doc”。我不确定我做错了什么，但我不想缩短名称。

以下是我的代码：

Imports System
Imports System.Collections.Generic
Imports System.Text
Imports iTextSharp.text
Imports iTextSharp.text.pdf

Public Class _Default
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim oReader As New iTextSharp.text.pdf.PdfReader("C:\4012014.pdf")
        Dim sOut As StringBuilder = New StringBuilder()

        For i = 1 To oReader.NumberOfPages
            Dim its As New iTextSharp.text.pdf.parser.SimpleTextExtractionStrategy
            Dim strLineText As String = iTextSharp.text.pdf.parser.PdfTextExtractor.GetTextFromPage(oReader, i, its)

            strLineText = Encoding.UTF8.GetString(ASCIIEncoding.Convert(Encoding.Default, Encoding.UTF8, Encoding.Default.GetBytes(strLineText)))
            sOut.Append(strLineText)
        Next

        oReader.Close()
        sOut.Append("<br/>")
        txtTest1.Text = sOut.ToString()

    End Sub

End Class
