"the files", "get URL" and Unicode File Names

Dear List Members,
I am trying to write a reasonably simple test script, which would iterate through every file in a chosen directory, and give me the md5 checksum for that file. I am coming across a problem, which *may* be related to Unicode, but I'm not certain. The algorithm is like this:
* user selects directory
* get list of files in directory (using 'the files')
* for every file in the list:
** get the file data stream (using 'get URL "binfile:..."')
** get the checksum
The function that gets the datastream using 'get URL' returns 'empty' in case it cannot find the file. I am finding, that when a file has certain accented or foreign characters in its name, 'get URL' is unable to find it - even though it is using the original unmodified string returned by 'the files'... What is most puzzling, is that this does not happen with *every* file that has an international character in it - files with french, spanish, german or even scandinavian characters fly through without a hitch. But if I have a file that has a "ĉ" (c+circumflex) or "ŭ" (u+breve) in its name, for instance, it chokes.
Am I doing something wrong, or missing something basic? - or did I hit a limitation, or bug?
Many thanks for any guidance,
Igor de Oliveira Couto
PS - the code in full, for those interested:
1) Make a new Mainstack, and add a field named "folderContents", and a button.
2) Put the following into the button's script:
answer folder "Please select a folder:"
if it is empty then exit mouseUp
local tDefault, tItems
put the defaultFolder into tDefault
set the defaultFolder to it
put empty into field "folderContents"
put the files into tItems
repeat for each line xLine in tItems
put "name=" & quote & xLine & quote after field "folderContents"
put " checksum=" & quote & fileDigest(the defaultFolder & "/" & xLine) & quote & return after field "folderContents"
filter field "folderContents" without empty
set the defaultFolder to tDefault
function hexDigest pvalue
local tRes, tMD5
put md5Digest(pValue) into tMD5
function fileDigest pFile
if there is a file pFile then
get URL ("binfile:" & pFile)
