how to get special characters like(square root , theta) ?

hi all

I am having a problem that i am having physics equations in my DB (ACCESS) and after that i am converting it to .txt file. After i convert it to text file i loose special characters like square root sign , theta etc.

then i have to serialize this file and pick data up from
this file.

Pls give me some ideas on it...... i have tried alot and unable to get any solution as of now..........

To key in the special characters like square root and theta etc. we copied the signs from word into Access.

Is it the problem with DB?

Help required urgently....

thanx in advance

use Writers and save chars in the file (not bytes)
char = Unicode char
byte = ASCII symbol

(or use some appropriate encoding)

hi heyhey

what i am doing is that when i convert the data from DB ro a .txt file or to a .doc file then only i loose the special characters. After that i serialize this (my generated .doc or .txt file).

Any ideas on that.........

I have tried it to convert it to unicode also but i  think i am making mistake somewhere......

Can anybody send some code for it?? or should i post my code what i have written......

help required urgently....

Thanx to all

Java String's contain Unicode symbols only. possible problems are
1. you cannot read the Unicode symbols from Access database (bad driver, bad encoding specified etc.)
2. you cannot write/read Unicode symbols to/from file.

I've already explained how to solve problem 2. problem 1. is more tricky and depends on your environment.

can you check if your Java app receives 'GOOD' Unicode symbols ? (print them as hex codes, not chars)
