SYMPTOMS
When you use the 5250 Client (Win5250.exe) with DBCS code pages, you experience problems when you type any of the following characters:
 * ' APOSTROPHE
 * { } BRACES
 * < > BRACKETS
 * : COLON
 * , COMMA
 * = EQUALS SIGN
 * / FORWARD SLASH
 * - MINUS SIGN
 * . PERIOD
 * + PLUS SIGN
 * &quot; QUOTATION MARK
 * ? QUESTION MARK
 * ; SEMICOLON
 * [ ] SQUARE BRACKETS
 * _ UNDERSCORE

You experience the following symptoms if the 5250 Client is configured to use a Host Code Page as follows:
 * If the 5250 Client is configured to use a Host Code Page of United States (037) on a system configured to use a DBCS code page (for example, Chinese, Japanese, or Korean) for the default System Locale, the 5250 Client's Input Inhibited (II) indicator is highlighted when you type any of the characters listed earlier.
 * If the 5250 client is configured to use a Host Code Page of Chinese GB (935) (or any other DBCS code page) on a system configured to use a DBCS code page (for example, Chinese, Japanese, or Korean) for the default System Locale, the 5250 Client displays question marks (?) or unrecognizable characters when you type any of the characters listed earlier.



CAUSE
The 5250 Client receives two WM_KEYDOWN messages for each of the special characters listed in &quot;Symptoms&quot; when configured to use a DBCS code page. One of the WM_KEYDOWN messages is for a virtual key code that was causing a problem with the key code conversion resulting in the problems described in &quot;Symptoms&quot;.
