|
157 |
* ASCII based protocols (eg. HTTP). The specifications (RFC2616, 2398) |

|
159 |
* says that the HTTP request URI should be escaped using a defined |
|
160 |
* mechanism, but there is no way to specify in the escaped string what |
|
161 |
* the original character set is. It is not correct to assume that |
|
162 |
* UTF-8 is always used (as in URLs in HTML 4.0). For this reason, |
|
163 |
* until the specifications are updated to deal with this issue more |
|
164 |
* comprehensively, and more importantly, HTTP servers are known to |
|
165 |
* support these mechanisms, we will maintain the current behavior |
|
166 |
* where it is possible to send non-ASCII characters in their original |
|
167 |
