XString to String on Unicode-System failed --> cx_sy_conversion_codepage

[Former Member]

Hi all,

I'm trying to convert a XString to a String; the content of the string is a png-image. In the past the conversion works, but a few days ago we did an Unicode-Migration of our system and now the conversion fails with the error "CX_SY_CONVERSION_CODEPAGE". I already tried to change the conversion which is used in the create-Method, but everything fails.

I really would appreciate if anybody could help me!

Best regards,

Stefan

I can not see any reason to do this. A Xstring holds binary data, and a string holds text data. A PNG bytestreams is not a text and cannot be converted to utf-8. UTF8 is only for text.

What exactly do you want to achieve?

Hi,

I need to encode the string to BASE64 as I need to add it into a XHTML-File. For example Firefox is able to open embedded images which are Base64-encoded.

Regards,

Stefan

Go to the repository information system (transaction SE80) and search for function modules. You will find a suitable one by searching fpr base64

Hi Rainer,

the FM "SSFC_BASE64_ENCODE" does what I need!

Many thanks and best regards,

Stefan
