| 141 | The BDB expects "binary" filenames (octet strings) for pathnames on POSIX |
140 | Perl on Win32 supports only ASCII filenames (the reason is that it abuses |
| 142 | systems, and "unicode" filenames (strings with characters potentially |
141 | an internal flag to store wether a filename is Unicode or ANSI, but that |
| 143 | >255) on Win32 (expecting a Unicode win32 build - win32 is a total mess). |
142 | flag is used for somethign else in the perl core, so there is no way to |
|
|
143 | detect wether a filename is ANSI or Unicode-encoded). The BDB module |
|
|
144 | tries to work around this issue by assuming that the filename is an ANSI |
|
|
145 | filename and BDB was built for unicode support. |
