I have a problem with JS HTML encoding
When I use non latin characters in window.alert() I get nonsense
If I use it in document html like ᄋ 弫 ᄋ ᄋ and so on then it is shown ok but when I put the same code encoding into the alert() box I get these ᄋ 弫 ᄋ ᄋ but not non latin text
How to fix it? What are the possibilities?

As long as you have valid encoding in your HTML file, everything is fine.

So, if you want to alert let's say greek characters use

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-7" />


and all texts will appear correctly. Most times however you will be fine with utf.

but window.alert() shows just numbers not non latin
