Asking for help on HTML Standards


Recommended Posts



Here is my current problem. We are developing a java web application suite and one of the screens requires a numerical input (currency). During one of the testing sequence, the tester entered the umlaut symbol (¨) which of course is an invalid character. In Ie, the page returned had the umlaut symbol changed to ¨ but firebird changes it to ¨. I know that both are still correct since they are just the umlaut symbol represented in different ways. But I cant find a decent documentation to back me up that this is not a defect on the software.


I tried creating a sample page like this


 This sentence has 3 kinds of umlaut: raw ¨, entity1 ¨ and entity2 ¨ 
 Modern browsers will display them equally without any problems.
       First box: 
       <input type="text" name="firstname" value="This sentence has 3 kinds of umlaut. ¨, 12¨00 and ¨">


and opened them using IE and Firebird. Both displays everything normally so I am deducing that the change is being done by the application server, but why differently for each browser? How do I prove to management that this is not unusual? Thanks for any help. :)




[edit] I thought it might be the http transport that is doing that but when I saved the html page in the root of a webserver (IIS), the umlauts are still being rendered as the umlaut symbol.

Nothing wrong with ¨


If you ask me, I think that Firebird is just smarter about this (it has a tendency to ;) ). If it really matters that much, then why don't you transform it into the appropriate value (hexadecimal notation or st.)? That way, no-one will know the difference, should only be one or two lines of extra programming.






[Edit: maybe you can use ¨ = Ampersand-Hash-168-semicolumn ?]

sorry guys if i didnt make myself clear. i am not involved in the programming per se. im just one of the tech support guys that finds out what the management/developers need.


i stumbled on this page (and together with darkelve's link) which further strengthens my theory that it is the browser that transforms the umlaut to its other entities. now i only need to find out a specific article that backs it up.


thanks again.

Found a few more links, sorry I can't be of more help...:


















It seems like number; is NOT official Xhtml and that &word; should be used, sorry for that confusion!
