This updates GenericEntry's filename handling to be more careful about Mac OS Roman vs. Unicode. Most of the work is still done with a CP-1252 conversion instead of MOR, but we now do a proper conversion on the "display name", so we see the right thing in the content list and file viewer. Copy & paste, disk-to-file-archive, and file-archive-to-disk conversions should work (correctly) as before. Extracted files will still have "_" or "%AA" instead of a Unicode TRADE MARK SIGN, but that's fine for now -- we can extract and re-add the files losslessly. The filenames are now stored in CStrings rather than WCHAR*. Also, fixed a bad initializer in the file-archive-to-disk conversion dialog.

* Win98 is quietly dying on large (20MB-ish) copies. Everything
|
|
* runs along nicely and then, the next time we try to interact with
|
|
* Windows, the entire system locks up and must be Ctrl-Alt-Deleted.
|
|
*
|
|
* In tests, it blew up on 16762187 but not 16682322, both of which
|
|
* are shy of the 16MB mark (the former by about 15K). This includes the
|
|
* text version, which is potentially copied multiple times. Windows doesn't
|
|
* create the additional stuff (CF_OEMTEXT and CF_LOCALE; Win2K also creates
|
|
* CF_UNICODETEXT) until after the clipboard is closed. We can open & close
|
|
* the clipboard to get an exact count, or just multiply by a small integer
|
|
* to get a reasonable estimate (1x for alternate text, 2x for UNICODE).
|
|
*
|
|
* Microsoft Excel limits its clipboard to 4MB on small systems, and 8MB
|
|
* on systems with at least 64MB of physical memory. My guess is they
|
|
* haven't really tried larger values.
|
|
*
|
|
* The description of GlobalAlloc suggests that it gets a little weird
|
|
* when you go above 4MB, which makes me a little nervous about using
|
|
* anything larger. However, it seems to work very reliably until you
|
|
* cross 16MB, at which point it seizes up 100% of the time. It's possible
|
|
* we're stomping on stuff and just getting lucky, but it's too-reliably
|
|
* successful and too-reliably failing for me to believe that.
