Parameters with special characters are passed through URLs, and special characters are lost.

Some symbols cannot be directly transmitted in the URL. If you want to pass these special symbols in the URL, you need to use their encoding. The encoding format is % plus the characters' ASCII code, that is, a percent sign %, followed by the corresponding characters' ASCII (hexadecimal) code value. For example, the Space Encoding value is "% 20 ".
If no escape character is used, the encoding will be treated as a special character defined in the URL.

The following table lists some special URL symbols and hexadecimal values.
1. In the + URL, the plus sign indicates space % 2B

2. the space in the space URL can be + or encoded as % 20

3./separate directories and subdirectories % 2f

4 .? Separate the actual URL and parameter % 3f

5.% specify special characters % 25

6. # indicates bookmarks % 23

7. & separator between parameters specified in URL % 26

8. = value of the specified parameter in the URL % 3d

ASPCode:
Function replaceparameter (STR)
STR = Replace (STR, "%", "% 25 ")
STR = Replace (STR, "+", "% 2B ")
STR = Replace (STR, "", "% 20 ")
STR = Replace (STR, "/", "% 2f ")
STR = Replace (STR ,"? "," % 3f ")
STR = Replace (STR, "#", "% 23 ")
STR = Replace (STR, "&", "% 26 ")
STR = Replace (STR, "=", "% 3d ")
Replaceparameter = Str
