Encoded string problem.

[mraiur]

Hi i have to make a rss veed that has to be made in two encodings everything is working but when i preview the rss -> "An invalid character was found in text content" .

And when i saw the code there where "?" or "!" or "~!" something like this . And when i searched to find some answears it was a bug in PHP 4 that is fixed in PHP 5 but the problem is that the servers the feed is on my boss still refuse to upgrade to PHP 5 .

So is there any way to overcome this problem?

BTW: 1-encoding is UTF-8 and 2-encoding windows-1251

thx all

Have you tried converting the characters to the HTML entities?

[mraiur]

I just tried it but still it continues to "break"...

[soycharliente]

So the formatting of the links won't work because you're using PHP4 to parse them? Do I understand correctly?

 

Can we see some code?

[mraiur]

its to much code to show i mean 1 i made was to cache all other is to read .

and the main problem is that a sentence witch is for example in bulgarian in utf-8 is 8 symbols  "Бългаски" but strlen shows its 16 symbols and substring for example cuts the string in the starting of the symbol ... i think

I don't know enough about specific encodings to be much help.

[mraiur]

Is there any other way to convert or something like that ... i tried converting the string to utf8 but yet again it still makes "invalid characters" ...

I'm fairly sure that you can only have one charset in a document, you cannot use a mixture of charsets. So if you are trying to use a mixture of charsets, your problem probably lies there.

 

How exactly are you using this combination of charsets?

[mraiur]

no i generate multiple files and the encoding witch has to be used is selected from the URL. So ?encoding=1 ( utf-8 files ) ?encoding=2 ( windows-1251  files )

[haku]

Its possible those characters don't exist in utf-8.

[mraiur]

but the problem is that they are shown normaly but i need to cut the string for example 100 chars and when i see the cutted string "invalid character".

[haku]

Ahh now I get it.

 

Is this happening in both files, or only the file with windows-1251 encoding?

[mraiur]

yea

Have you tried iconv? What encoding is the source in?

[haku]

yea

 

That didn't really answer my question, but it's ok, I'm pretty sure I understand your problem. You will need to enable the mbstring (multi-byte string) library in php (it's not usually enabled by default), and then use the mbstring functions to cut the feed at 100 characters. This should solve your problem.
