Btw: only 3 urls allowed – urls made nonworking; please remove space between first and second slash.

Please go to this page: http://www.sevas.com.tw/chi/product_content.php?id=40

there you find five download links; two PDFs with chinese names (1, 3) and three installers with latin names (2, 4, 5) that do not make problems.

Go to the first PDF-file Link and try several ways of downloading it:

晶片卡讀卡機簡易故障排除 下載

when clicking on the link, FDM gets following link:
http:/ /www.sevas.com.tw/uploadfile/????????????.pdf

in the FDM-File-Name-List you see a filename "index.html
if you try to download that, you get a "index.html stopped; access denied, invalid user name or password" error

when right-clicking the link and copying the link, FDM gets following link:
http:/ /www.sevas.com.tw/uploadfile/%E6%99%B6%E7%89%87%E5%8D%A1%E8%AE%80%E5%8D%A1%E6%A9%9F%E7%B0%A1%E6%98%93%E6%95%85%E9%9A%9C%E6%8E%92%E9%99%A4.pdf

if you manually replace the FDM-link with the correct link (that was correctly put to clipboard):
http:/ /www.sevas.com.tw/uploadfile/晶片卡讀卡機簡易故障排除.pdf
you get the same "index.html"-file to download – what is not working ...

... so you cannot tell "get a normal browser then it's working" ... the problem are the chinese characters that cannot be handled ...

second file:

ATM晶片讀卡機使用手冊 下載

http:/ /www.sevas.com.tw/uploadfile/IC??????-?????.pdf
trying to download that results in "IC stopped; file not found" error

if you right-click "download with FDM" following link is got:
http:/ /www.sevas.com.tw/uploadfile/IC%E6%99%B6%E7%89%87%E5%8D%A1%E8%AA%AA%E6%98%8E%E6%9B%B8-%E9%81%A9%E7%94%A8%E5%8F%B0%E7%81%A3%E5%8D%80.pdf

the downloaded file gets the name: IC______-_____.pdf

copying the link to the clipboard makes FDM take following link:
http:/ /www.sevas.com.tw/uploadfile/IC%E6%99%B6%E7%89%87%E5%8D%A1%E8%AA%AA%E6%98%8E%E6%9B%B8-%E9%81%A9%E7%94%A8%E5%8F%B0%E7%81%A3%E5%8D%80.pdf

the correct link is:
http:/ /www.sevas.com.tw/uploadfile/IC晶片卡說明書-適用台灣區.pdf

so you cannot download these chinese named PDFs with FDM ...

Please make unicode working correctly, thanks!
