I18N Tests: Character encoding detection 3

   Results

This is one of a set of pages that examine how a user agent handles character encoding detection.

The tests on this page check how characters in the C1 range of ISO code pages (ie. 0x80-0x9F) are displayed for pages when ISO 8859-1 and ISO 8859-15 encodings are declared using HTML5's charset="encoding" syntax, and whether their presence affects the encoding reported by the user agent. None of the tests link to pages that have encoding information in the HTTP header. Where encoding information is supplied, it is via the in-document meta element.

For information about the C1 range, see HTML, XHTML, XML and Control Codes.

1 ISO 8859-1, C1 cp1252

Objective: When the encoding is declared to be ISO 8859-1, are Windows 1252 characters in the C1 range displayed, and what encoding does the user agent report?

The meta encoding declaration says ISO 8859-1. The C1 range characters included are characters in the Windows 1252 code page.

Click on the link and check (a) what the encoding setting is in the browser chrome, and (b) whether you see the characters described on the page.

2 ISO 8859-1, C1 cp1256

Objective: If we change the C1 range characters to be only those that are not in Windows 1252, but are in Windows 1256, does this make a difference?

The meta encoding declaration says ISO 8859-1. The C1 characters are 0x81, 0x8D and 0x8F.

Click on the link and check (a) what the encoding setting is in the browser chrome, and (b) whether you see the characters described on the page, and whether those are different from the results of test 2.

3 ISO 8859-15, C1 cp1252

Objective: Are C1 characters displayed when the encoding is declared to be ISO 8859-15, and what encoding does the user agent report?

The in-document meta element says that this page is encoded as ISO 8859-15.

Click on the link and check (a) what the encoding setting is in the browser chrome, and (b) whether you see the characters described on the page.

4 ISO 8859-15, C1 cp1256

Objective: If we change the C1 range characters to be only those that are not in Windows 1252, but are in Windows 1256, does this make a difference?

The meta encoding declaration says ISO 8859-15. The C1 characters are 0x81, 0x8D and 0x8F. The C1 range characters are only

Click on the link and check (a) what the encoding setting is in the browser chrome, and (b) whether you see the characters described on the page, and whether those are different from the results of test 3.
