Permit to use the € symbol in the Pixie html5 image editor

This html5 image editor is simple and powerfull: [login to view URL] I just need to patch one thing: Permit to insert from the text editor the € symbol from windows systems like using as normally "ALT GR+E" instead in that image editor it doesnt' works and in many other html 5 image editors it works, but I need to use this html image editor. (on apple it works well, using as normal Alt+E for european and alt+shift+2 for not european). I just neeed to be able to use the ALT GR+E to create the € symbol in this image editor instead of the uncomfortable "ALT+0128". Bid to me and I will send you the script, then you can show me online if you solved the problem, in that case, I will choose you and pay you.
