#1 source cannot compile

[yyh]

Dear Stefan:
Thank you for your job and I am a student in China ,I
have downloaded the .zip file for learning .but when I
open it in jbuider7, I can not compile SmsPduCodec.java
due to a error ""SmsPduCodec.java": Error #: 106 :
unclosed character literal at line 259, column 52" .
then I set the Jbuilder project's Encoding
as "iso8859_1" but the error remains.
and I opened the file with windows notepad , I found
some chars cannot be displayed successfully:

// construct GSM alphabet to/from ISO mappings.
char[] gsmiso = { 0, '@', 1, '?, 2, '$', 14, '?,
15, '?, 17, '_',
91, '?, 92, '?, 94, '? ,
95, '?, 123, '?, 124,
'?, 126, '?, 34 , '"' , 5 , '? , 4 , '? };

Would you mind to tell me why did it happens? did it
because I am useing a windows 2000(Chinese Edition)?
