Find and replace text on PDF document - charset

[kupka.vojtech]

Hello,

I am trying to Find and replace text on PDF document in VB.NET according to this tutorial:
Tutorials > .NET > Spire.PDF > Program Guide > Text > Find and replace text on PDF document in C#

I came across one problem: string I am replacing original text with contains characters witch are not interpreted well (like šřáĚŽÝ ...).
Could you help me with this issue?

Thank you so much!

Hello,

Thanks for your inquiry.
Please kindly notice that if you use the Czech to replace, you need to set the font style to Czech font to avoid font garble. You can refer to the following code:

Code: Select all

' Defines a font
        Dim font As New PdfTrueTypeFont(New Font("Your Czech font", 12.0F, FontStyle.Regular))

If this solution does’t help you, please offer the following message to help us reproduce your issue and work out a solution for you. Thanks for your assistance in advance.

Hi Abel,

thank you for your quick answer! Unfortunately, text replacement still does not work well.
Here is what I do:

Code: Select all

Dim font As New PdfTrueTypeFont(New Font("TimesRoman", 12.0F, FontStyle.Regular))
Dim lBrush As PdfBrush = PdfBrushes.Black
Dim x As Single = lPosition.X - lMarginX
Dim y As Single = lPosition.Y - lMarginY

lPage.Canvas.DrawRectangle(PdfBrushes.White, lFind.Bounds)
lPage.Canvas.DrawString(aNewText, font, lBrush, x, y - 2)

When I call function

Code: Select all

ReplaceText("__APPROVED_BY__", "Alžběta Řízečková")

the result of replacement will be "Alžb ta Xíze ková" as you can see at the screenshot from pdf:

So it seems like some Czech characters work, but not all of them. Do you please have some idea what to try next?
I can´t send you the pdf, because it contains our customers data. But I could create some example pdf instead if necessary.

Thank you very much!
Vojta
