weird symbols

nasht

Hi,

I am manipulating data to make a csv file, but I run into a wierd symbol everywhere.
Look at the following extract:

"Hydroxypropylmethylcellulose, Petrolatum, Titanium Dioxide.Replenix Fortified CleanserPurified Water, Sorbitol, Cetyl Alcohol, Stearyl Alcohol, "

You see those ? I hope they'll appear too when I post this message...

I want to take them out.
I'm doing a

$field = str_replace("\n"," ",$field);
$field = str_replace("\t"," ",$field);
$field = str_replace("\r"," ",$field);

But I don't know how to delete those symbols, since I don't know what they're supposed to be.
They appear both on the actual html page and on the database using phpMyAdmin.
When I try to fwrite() them on a file, they appear as new lines.

Any ideas?

Thx.

Let me correct something.
I said than fwrite() makes them appear as new lines.
This is actually not true:

WORDPAD interprets them as new lines.
If I open it with other text readers, they still show up as this square symbol.

Also, I added some str_replace():

	$field = str_replace("\n"," ",$field);
	$field = str_replace("\t"," ",$field);
	$field = str_replace("\r"," ",$field);
	$field = str_replace("\a"," ",$field);
	$field = str_replace("\e"," ",$field);
	$field = str_replace("\f"," ",$field);
	$field = str_replace("\v"," ",$field);

Still there...

it is probably just a \n by itself. windows requires newlines be \r\n, where unix just uses \n. normal textboxes in windows will show a block character if a single \n is present, but wordpad uses a different class so it will work with \n or \r\n.

No it can't be,
As I said earlier, I am already deleting all
/n, /r, /a, /e, /f, /v

(see my code above).

Do you have something that would allow you to look at the actual byte values of the characters? (If you don't, you could whip something up in PHP to look through each character of the file and echo its ord()). As you know, the blocks are characters for which the given font doesn't have an appropriate glyph. If you knew what those characters were you'd have something more to go on than just guessing what they might be.
