- There have lately been some discussions about setting the font path for
- AUIS applications. Currently xim.c does an XSetFontPath to include
- .../andrew/X11Fonts (or some site specified value) as the last entry on
- the fontpath. This is bogus because it looks up the fontpath on the
- client machine and then passes it to the server, which may be on an
- entirely different file system.
-
- There have been various suggestions for guessing what fontpath to tell
- the server, but none seems foolproof. There is the suggestion that some
- program be run before starting the X server or before running an Andrew
- application. All of these require care on the server end and will make
- Andrew look bad if this care is not taken.
-
- My own pet solution is to reduce the problem by not using fonts for the
- various special purposes they have been put. Instead, any application
- desiring special characters would build them in a bitmap file. Then the
- bit map would be loaded in the client and transferred to a pixmap in the
- server from which the images would be drawn on the window.
-
- There would still be a problem with files that utilize the symbola font,
- but this would not affect every application as does icon12 and shape10.
-
- At the moment, switching to bit/pixmaps is but one alternative and we
- are not yet implementing anything; we are busy on other tasks. Should
- someone wish to offer code for this or another solution, we would be
- delighted.
