Error: Invalid UTF-8 sequence when reading txt file from hard disk [message #16656]

Hi,
I am having troubles reading a text file from disk.
I created the txt file with windows XP (PT) notpad. Then, in a Upp I use the fopen and fgets to read file lines.
When I add the lines read to a ArrayCtrl I cant see the accents. If I try to display it using the Exclamation message box function it displays "ERROR: Invalid UTF-8 sequence".

Any doc to read about how U++ handles different char sets?

Any help would be appreciated.

Thank you,

Alex
Env:Win XP (PT), U++ 2007.1

1. Are you shure it is really a UTF-8 text? If not, better test it in some UTF-8 capable viewer.
2. Did you switch application charset to UTF-8 by calling SetDefaultCharset(CHARSET_UTF8); ? U++ should know the text labels you use are in UTF-8.
3. It would be easier to help when we see your code where you load and show these strings.

But, does u++ just deals with UTF-8? Is UTF-8 the default charset when noting is configured ?

1) It does Smile

2) Sorry, I don`t remember exactly. May be not, default could be EN-US, or something like that. Besides, calling 1 operator at program start doesn`t look like a great deal of configuring. Does it?

I think UPP default is not UTF-8 in Windows, and I'm not sure about Ubuntu.
I wouldn't care about default setting anyway, just set it up by hard way and forget about it.

If I try to display it using the Exclamation message box function it displays "ERROR: Invalid UTF-8 sequence".

The problem most likely is that UTF-8 is default encoding of QTF texts. If you submit a text without explicit encoding enforced via QTF commands, parser expects UTF-8.

Note that QTF encoding is different (has to be!) from default application encoding.
