Hi Carl:
Great minds run in the same gutter! It would seem that rebol's
native funcs aren't taking this into consideration.
; I just churned this out. Hopefully someone has a better
; solution, if not, pointers are welcome to docs on
; other chars to be escaped.
url-str: def[str[string!]][
encode: [#"%" "%25" #"&" "%26" #"=" "%3D" #" " " "]
new-str: make string! (length? str) * 2 ;oh, just an estimate
repeat char str[
either found: select encode char
[append new-str found]
[append new-str char]
]new-str
]
