It seems clear why the page won't load. 
To load the site correctly, program must complete the following steps:
1. Download page from url
2. Translate page from UTF8 to ANSI (page charset to ansi)
3. Find links.
4. Translate founded links to UTF8 (page charset)
5. Then translate step 4 links to canonical URL (escape sequences)
6. Then download links
It seem step 4 doesn't run
