forms, urls and special characters

Hello, i have a problem, google has a [URL=http://translate.google.com/translate_t]translating tool[/URL], when you submit a text in the propper field with the proper languaje selected, everything works fine, Now, when you send all the needed variables via url to that page, i get ???? when using korean languaje, however if i use regular text (ASCII) there is no problems, i know it probably can be solved by encoding the text, but if i need to change the text, sending different strings everytime i is complicated…
is there a way around that?, so i can send special characters through urls?

here is an example of what happens…

[CODE]
This one sends the korean chars
translate.google.com/translate_t[URL=http://translate.google.com/translate_t?text=여보세요&langpair=ko|en&hl=en&ie=UTF8&oe=UTF8]?text=[COLOR=DarkOrange]여보세요[/COLOR]&langpair=[COLOR=DarkOrange]ko|en[/COLOR]&hl=en&ie=UTF8&oe=UTF8[/URL]

and this one sends regular text
translate.google.com/translate_t[URL=http://translate.google.com/translate_t?text=Hola&langpair=es|en&hl=en&ie=UTF8&oe=UTF8]?text=[COLOR=DarkOrange]hola[/COLOR]&langpair=[COLOR=DarkOrange]es|en[/COLOR]&hl=en&ie=UTF8&oe=UTF8[/URL][/CODE]

what i basically want is to display that page in a popup window with my own settings for it, i was trying to change the url of it to a new one containing the new text to be translated by referencing the window through javascript
(working with ASCII chars everything works the way i want to)
Thanks ?

EDIT: if you did not understand what i wanted, please see the link below, thats the effect i want, it is working almost the way i want to BUT only if you replace the korean characters in by ascii and press google translate button
