Special Characters and Image name

[bsarlo]

Hi all.

I've searched through the web and couldn't find the solution to my problem.

I have a site that works with php, mod_rewrite, apache, and linux.

Whenever I try to see a picture which the name has special characters, then it wont display it.
This are the tests I've made.

The file name is Espa%F1a.jpg

When I write directly to the browser url bar, this are the results:

When I point to Espa%25F1a.jpg, It shows the file.
When I point to Espa%F1a.jpg, it doesn't work and shows up Error 404
And when I point to España.jpg it rewrites the url to Espa%F1a.jpg and shows an Error 404


Any help will be much appreciated.

The reason is simple: %25 is the urlencoded form for the percent symbol, %

When "Espa%25F1a.jpg" is used, the browser converts this to "Espa%F1a.jpg" and uses that.

The solution probably involves using rawurlencode() or urlencode().

Hey laserlight, thanks for your reply, but I think I understand this part, but just can't understand why, the "%" special character is represented with itself plus "F1"... I just can't understand this.

Anyway, here are other tests I've made so maybe it's more clear what the problem could be, but I still cant understand it.

For example, if I have now a file called "Blumensträußen test.jpg" (with special characters and a space), here are the results from my tests:


If I enter the url Blumensträußen test.jpg into the address bar, it will translate it and show the image correctly, and that will be "Blumenstr%E4u%DFen%20test.jpg"
Now our problem. The same wont work within an html page. If I call for an image "Blumenstr%E4u%DFen%20test.jpg" it wont show it, or even calling "Blumensträußen test.jpg" wont do it, and here is where my project is stuck till I find a way out... :S


thanks again for the support.

The '%' character is represented as %25 in urlencoded form.
"Espa%F1a.jpg" in urlencoded form is "Espa%25F1a.jpg"
If you did not urlencode this filename, then %F1 would be interpreted as the character represented by %F1 in urlencoded form, hence the filename used would be incorrect.

Interestingly, the urlencoded form of "España.jpg" appears to be "Espa%C3%B1a.jpg", not "Espa%F1a.jpg", at least to me.

If I call for an image "Blumenstr%E4u%DFen%20test.jpg" it wont show it, or even calling "Blumensträußen test.jpg" wont do it
That's unusual, as far as I can see the rawurlencoded form is correct.

I dont have any way to test your problem, so you'll have to think about it and construct your own tests, or maybe post some code.
