dhtmlxCombo : problems with accents

Hello, dhtmlxCombo is a very nice script !

I tested your demo "dhtmlxCombo. Working with big datasets", and there is a problem, who can be repeated as often as it is usefull for your tests :

By example :
-1- you type "cabre", combo displays "cabré". OK
-2- you type "cabré" (whith the accent), combo displays "cabré". OK
-3- you type "echappe", combo displays "échappés". OK
-4- you type "echappé" (with the accent), combo DO NOT suggest "échappés". NOK !
-5- you erase and type only "e", combo do not content suggest "échappés" !?
After this error, combo's behavior become surprising with accents.
Maybe a problem with the first letter ? if you type the only letter "é", you will never get "échappés" will never appears !

I use IE 6.0

I would like to use your script with main navigators (IE, Mozilla Firefox, etc.) with accents...
A solution please ?

Many thanks
Jean-Michel

The behavior depends on used server side code, by default copmonet uses utf based escaping for data requesting. When non-utf code used in server side used it will result in above behavior. To fix issue you can locate next string in dhtmlxcombo.js 
      "&mask="+encodeURIComponent(text);
and replace with 
      "&mask="+escape(text);

>>you type "cabre", combo displays "cabré". OK
actually it is a not expected side effect, the search functionality of MySQL doesn't separate normal and accented chars, behavior will be different for client side filtering. 

Many thanks for your help. I will try that.
