url encode latin-1 characters

[Lurker]

I want send latin-1 string to web server by url parameter

urllib.quote return just symbol code with preceeding percent for every
non-ascii character:
#>ustr = 'Ü'
#>urllib.quote(ustr)
'%9A'

but this seems to be wrong because server response contains my
parameter and it differ from original (for example 'Ü' became '[')
