42990 - alert('') not able to display ö

Status: RESOLVED WONTFIX

(Core :: JavaScript Engine, defect, P3)

Description

[Sebastian Späth]

It seems as if current builds (06/17) are not able to display characters like 
ö & ... in a JavaScript alert. They will just display the unencoded 
character series.

Oohh, NS4 displays them neither, is that intended behavior? 
L10n will be crying...

I have absolutely no clue which component this bug should go to, Asa, would you 
be so kind...

Could yo provide a samle testcase? Moving to Javascript engine, but could be a
DOM issue.

"Script data ( %Script; in the DTD) can be the content of the SCRIPT element and 
the value of intrinsic event attributes. User agents must not evaluate script 
data as HTML markup but instead must pass it on as data to a script engine.

The case-sensitivity of script data depends on the scripting language.

Please note that script data that is element content may not contain character 
references, but script data that is the value of an attribute may contain them. 
The appendix provides further information about specifying non-HTML data."

So, inside a script, & will stay &, while as part of an event like 
onload, it will be parsed before given to the JS engine.

I just tested it using onload="alert('ä&')" and that worked fine.

I strongly doubt the JS engine parses & into an &, since it's expecting raw 
data, using Unicode where needed, not HTML/SGML.

I'll look for the ECMAScript specs and study them, and see what it says.

Tentatively marking this WONTFIX as suggested by doron.

Inside <script>...</script> you can use either \uXXXX with the correct character 
encoding specified (or know which is the default), or directly use characters 
like ö.
