How to browse a font by characters from a given codepage?

Question

Most of the font manager tools display characters of a font grouped by subsets of the Unicode character set. Is there a tool that displays the characters grouped by the particular code page that a given font supports? I.e. for the font Arial, display all characters that are part of the Windows 1252 code page.

//edit:

The only program that does exactly this is Windows Character Map:

The problem with Character Map is that:

• I'm not sure how do entries in the menu map to actual code pages. For the Windows* ones, one could use this table (i.e. Windows: Central Europe maps to Windows-1250), but what about the DOS ones
• certain code pages are missing in the menu
• inside of the properties of the font file, there is a list of code pages that a given font supports. Seeing those code pages would be helpful, if possible
• there is no way that I've found to see the character code from the code page selected, only the UTF-16 character code is shown (U+XXXX), though for this one could use the conversion table.

Thanks to Jukka, what I ended up doing was to swap the font on the webpage that displayed the code page to Unicode mapping. Hopefully it doesn't matter if glyphs of the font are accessed through the Unicode code (UTF-8 on the webpage) or through the code page code. Here is the Stylish script to do just that:

@-moz-document regexp("http://www\.fileformat\.info/info/charset/.*/grid.htm.*") {

    body {
        font-family: 'Magneto', 'Unicode BMP Fallback SIL'  !important;
    }
}
