UTF8 problem with WinXP of other languages

I found a problem with UTF8 when using SmartFTP 1.0.981.13 2004-02-20 03:55:19 logon to ftp://ftp.smartftp.com/ .
In WinXP's Regional and Language Options -> Advanced -> Language for non-Unicode programs, the result from above URL changes when the language is changed. With Regional Options fixed for English (UK), Location fixed for UK, Supplemental language support both for Install files for complex script and East Asian languages checkboxes checked.
Apart from the folder ANSI here are the other folders shown when the Language is changed.
UK English, Farsi, Urdu, Vietnamese, Indonesian, Russian : no problem, all UTF8 folders are shown
Thai : only one folder shown (Eg kan eta glas utan . skada meg)
Chinese (PRC), Japanese, Korean : none are shown
No problem at all when use MS ftp.exe no matter what the language is (can see all the folders in the command prompt even though sometimes with strange characters).
Cheers.

I cannot reproduce it here.

You can change a settings in Settings->Transfer "Listing Encoding". It may changes the behavior.

Auto is the default.

The "Language for non-unicode" setting in XP shouldn't affect SmartFTP at all as it's a unicode application. The conversation from the server is UTF8 -> Unicode (no ANSI here as well).

Forcing UTF8 does help a bit. Now I can see all the folders BUT can't go into all of them. Here is the error when the language is set to Japanese:
The other folders are ok.

Here is when the language is set to Thai. Without forcing UTF8, I can see only one folder in the file listing AND can enter that folder.

Cheers.
