>Summary: Bad escaping: wrong assumption that char is unsigned

Initial Comment:
curl_easy_escape compiled with recent gcc (4.2.1 built by ArchLinux) works wrong: it replaces all upper half characters with '%FF'.

In curl-7.17.0/lib/escape.c curl_easy_escape on line 123 (snprintf(&ns[strindex], 4, "%%%02X", in);) assumes that char (in) is unsigned. This assumption is wrong.

The simplest patch is to replace 'char in;' with 'unsigned char in;' on line 62.

How to apply attached patch:
cd curl-7.17.0
patch -p1 -i ../signedchar.patch
