How to handle user preference which has "_" and " " in the name

Question

Hi Experts,
I have a question how to handle value which has like "_" and "space" etc in user preference.
If setting "a_b-c d", I could not retrieve this because it's escaped in database.
So this code can't get value even though I can set it.
Is there any restriction of name? Is there any documentation how to code user prefernece which has non alphabet and number in the name?
I know it's possible to handle the data like adding escaped data. But I don't think this is the best way to retrieve the data. Because nobody confirm it's not problem in the future.
Could you tell me the best way to get these user preference?
Thanks in advance,
Masaaki Tada

String val = oPortletRequest.getSettingValue( SettingType.User, "a_b-c d" );String hoe = oPortletRequest.getSettingValue( SettingType.User, "abcd" );out.println( "a_b-c d: " + val );out.println( "abcd : " + hoe );
oPortletResponse.setSettingValue( SettingType.User, "a_b-c d", "aiueo" );oPortletResponse.setSettingValue( SettingType.User, "abcd", "bbbb" );%>

Plumtree recommends that user preference names have only alphanumeric characters in them (a-z, A-Z, 0-9). Any non-alphanumeric characters will be encoded by the EDK.
I strongly suggest that you change your user pref name to something that's alphanumeric. However, if that is not possible, you can use the following workaround: in the web service editor, enter the encoded name for the user pref. There are several ways to get the encoded name.
One way is to encode the pref manually, yourself. Plumtree uses the %u encoded format: each non alphanumeric character is converted into %uxxxx, where xxxx is the Unicode representation of the character. For all ASCII characters, just look at the ASCII hex chart. For example, character "-" has a hex value of 2d. So, a preference name "jane_pref" would be encoded to "jane%u002dpref", and you'd enter the latter value on the preferences page in the web service editor.
The other way to find out the encoded value is to set a preference programmatically and use the HTTP tunnel tool to look at HTTP traffic between the portal server and remote server. The remote server will be sending a HTTP header to the portal server (the header name will probably be CSP-User-Pref) and inside the header you should see the pref name, encoded with %u. Just copy it out of there and into the web service editor.
Hope this helps,
