9.2 convert ASCII to UTF8 welsh language

Question

hello
I have a 9.2 ascii database that i cant convert to UTF8 yet
1 for an output (util file) i need to convert an ascii text string to utf-8 on export
2 i have two characters that are not supported by ascii, ŵŷ the users will represent these by typing w^y^
I tryed using UNISTR but non of the characters below are corectly converted
SELECT UNISTR(ASCIISTR( '剔搙)) FROM DUAL ;
how would you recomend converting a ascii latin 1 extended string to UTF-8 for export?
is it sencible to use the character replacement plan above for ŵŷ?
thanks
james

Answer 1

Probably the unconverted characters are not contained in the first charset.
If this is right.
http://en.wikipedia.org/wiki/Windows-1252
...there is no conversion for values outside the first charset.
But I may made a mistake.
Are you sure Â, â, î, Ê, ê and ô are in the 1252 charset?
I am not able to see if there is a difference between the similar chars in the table on wikipedia and the ones you posted, that is why I asked.
Anyway this output seems to verify my indication.

1 row(s) retrievedSome characters are not supported on my DB so try these queries on yours to prove it.
