Why do certain accented characters display properly in 3.0 but not in 4.0 or 4.1?

There is a character (and its uppercase counterpart) that was not part of the standard windows encoding file when Version 3 was released. Wolfram Research, recognizing this oversight, added a custom assignment for this character.

For Version 4.0 and later, this character was added to the standard windows encoding file. This means that the character assignment value changes between Version 3 and later versions and will not display properly in notebooks created with a different version.

To get the character to display properly in newer versions, you can do a search and replace for the two character encoding strings:

∖:017e replaces ∖:f29e

∖:017d replaces ∖:018e

Please remember to delete the cache ID for the notebook when making changes to a notebook outside of Mathematica®. The line is:

(*CacheID: 232*)

The updated WindowsANSI.m file below is available for download and can be placed in Version 3 layouts to allow it to use the industry standard for this character.

The file should be placed in:
