The hexadecimal bytes are clear enough to me: 0x31 is a "1", 0x32 a "2", 
and 0xE5 is *not* an ascii character but, in Unicode, a lowercase "A" 
with a small circle above it (don't know how to name it).

This could be a date in italian/european format, like 25-12-2008 or 
25/12/2008 (Christmas). I have seen that browsers, which can display 
different character sets, sometimes display a strange character instead 
of the normal one for the apostrophe. This can happen to dashes or 
hyphens and, who knows, to other characters too. It remember that was 
caused by an incorrect implementation of ISO-8859-xx.

One quick way to verify this is to change the date, for example to 
02-01-2009, and run the test again: if the hex bytes come out like 0xE5 
0x30 0x31 0xE5, then this is the problem. Or, using a more scientific 
test like Benoit suggested, do an hexdump and see if there are strange 
characters: chars less than 0x20 are not good, and so are those greater 
than 0x7f.

Supposing that this is the problem, I don't know what to say anymore - a 
bad encoding implementation (mysql or gambas fault) or bad 
pairing/coupling of encodings (programmer's fault) has to be found 
somewhere...

Cheers,
