SV: [mapguide-users] Get Garbled in SelectionPanel (fusion)

[Måns Beckman]

Hi, 

I have had a quick look at this because I have the same problem with Swedish chars "ÅÄÖåäö". I didn't get the utf8_encode to work for me either, but I did see some interesting things in the JSON code.

Here is the output I get when I select one feature in the map.

{"layers":["Vägar-Text"],"extents":{"minx":93434.546699998,"miny":6217429.1614999,"maxx":102313.2338
,"maxy":6224177.9349999},"Vägar-Text":{"propertynames":["FeatId","GATUNAMN","VAGNR","ZOOMLEVEL"],"propertyvalues"
:["FeatId","GATUNAMN","vägnummer","ZOOMLEVEL"],"propertytypes":[7,9,9,9],"metadatanames":["dimension"
,"bbox","center","area","length"],"numelements":1,"values":[["1518","Christinelundsvägen
 (111)","111","level0"]],"metadata":[["","","","",""]]}}



What I think is really interesting is that:
The layers property is encoded correct - "layers":["Vägar-Text"]," 
The property values are encoded correct - "propertyvalues":["FeatId","GATUNAMN","vägnummer","ZOOMLEVEL"]
But the values are encoded wrong - "values":[["1518","Christinelundsvägen (111)","111","level0"]] should be "values":[["1518","Christinelundsvägen (111)","111","level0"]]



The same data displays OK in the Ajax-viewer so it's not the values that are wrong. I'm kind of guessing that the error is in the place where we get the values from, and should be corrected there, and not in Selection.php.

Best regards
Måns

Darn - ok, I just went and looked at what utf8_encode actually does  
(!) and its not what we want in this case, it encodes iso 8895-1  
characters as utf8 which is probably the generally useful case for  
most people but doesn't apply to double byte character sets.

I really don't understand character encoding at all, but I am willing  
to incorporate changes into fusion to make this work as long as it is  
generic enough to work in the common cases that I deal with too.   
Unfortunately I don't have the time to put into becoming educated  
about this right now ...

Can you spend some time looking into these functions (and the user  
comments that follow):

http://www.php.net/manual/en/function.utf8-encode.php
http://ca3.php.net/manual/en/book.iconv.php

and let us know what you find out?

Cheers

Paul
