problem when using ConvertFromUnicodeToUtf8

[devian1001]

Hi everyone,

i have a problem when i try to use CnvUtfConverter::ConvertFromUnicodeToUtf8.

I have a function like that

void CMByDB::addNewItem(TDesC& fileName, TInt fileType)
{
//since my fileName column type is EDbColText8 so i do a conversion like that
//convert from 16bit to 8bit
TBuf8<768> aFileName8;
CnvUtfConverter::ConvertFromUnicodeToUtf8(aFileName8,fileName);
.....
}

but the output of before and after conversion is not same.

Do you know what is the problem ? Please give me suggestion how to solve it.

Thank you very much.

but the output of before and after conversion is not same.

What kind of difference have you experienced?

[devian1001]

the character format is all changed. this is what i have experienced. please give me ideas or other solution to convert between 16 bit descriptor and 8 bit descriptor.

Thank you so much.

Are you sure you want to use UTF8, with it characters are not presented as bytes really. Maybe you should try something else, like IS0 8859-1 for example..

If you use standard ASCII characters (so the upper 8 bits of your Unicode characters are 0), TDes8::Copy(const TDesC16&) and TDes16::Copy(const TDesC8&) may also help.

sorry yucca, my mistake, i am using the ASCII. I have try what wizard suggested, but the characters in the target also changed. Any other ideas ?
Anyway, thank so much for your help.

Why don't you post the text that is causing the problem?

Thanks for your reply.

My source descriptor contains a file path, forexample c:\data\immages\pictures\file1.txt, when i try to use TDes8::Copy(const TDesC16&) like Wizard suggestted. the destination descriptor is not same as source one. The destination looks like this C\aaIae\itrstx0.x╠╠╠╠╠╠╠╠╠╠╠╠╠╠╠╠╠

Please give me suggestion how to solve it. thank you
