QRCode

rbuser

Hi,
how to encode UTF8 to QRCode? Is it some setting or do I have to do some
encoding of data string?
For example: ešcržýáíéúuó

Thanks

Hi Roman,

The Data property for the barcode is a String. Starting with Delphi
2009, String = UnicodeString (UTF16). You can convert the UTF8 String
to a UnicodeString in order to get the output you want.

For older versions of Delphi String = AnsiString.

Hi Nico,
you don't understand me:-). I'm using Delphi XE3, so I'm in Unicode.

I have for example this text in DB in NVARCHAR:
príliš žlutoucký kun úpel dábelské ódy

So I create report, set QRCode to it and join to right data field.
I see text under QRCode and it looks good.
But problem is if I try to read the QRCode. I try to change coding: Byte,
AlphaNumeric, Numeric.
I used several QRCode readers but only one (Google) can read good (QRCode -
Byte).
I searched on internet and found out that it is necessarily to add preamble
for UTF8...
But how?

Thanks

This issue is being handled via email.

The QRCode component in ReportBuilder currently supports ANSI encoding
only. We will consider enhancing this to support UTF-8 for a later
release of ReportBuilder.

Hi Nico,
I tried new release 15.01 and I had problem with QRCode:

1. create new application in Delphi (I have Delphi XE3)
2. put TppReport on the form and start Report Designer...
3. put 2DBarCode
BarCodeType = bcQRCode
Data = ešcržýáíéúóu
QRCodeSettings.CharEncoding = bceUTF8
4. click on Preview

Now you are wainting and wainting and wainting... Or you can see Out of
memory...
