Bug 34870: Perform UTF8 encoding before redirection

Bug 34870: Perform UTF8 encoding before redirection

Display special characters correctly when writing off an invoice.

The issue arises because pay.pl does not perform UTF-8 encoding on the “notes” parameter before redirecting the page. By using uri_escape_utf8, characters with a code above 255 are also UTF-8 encoded. Then, paycollect.pl can collect the information without any trouble.

This patch work with “;” and “:” characters.

TEST PLAN
1) Go to any patron profile > Accounting
2) Click “Create manual invoice”
3) Fill the fields and click the “Save” button
4) Repeat steps 2 and 3
5) Click “Make a payment”
6) Add a note with special characters for each one (e.g., éçö)
7) Select the created invoices and click the “Write off selected” button
8) In the note field, you should see “�” symbols where the special characters are supposed to be
9) Click the “Cancel” button
10) Now add a note with “:;” for one of the invoices
11) Select the invoices and click the “Write off selected” button
12) You should see a page with an error 500
13) Go back to the “Make a payment” page
14) Apply the patch
15) Add a note with special characters for each one (e.g., éçö)
16) Add “:;” to one of the note fields
17) Select the invoices and click the “Write off selected” button
18) Now the special characters are displayed correctly
