And more, "OverTheSpot" is the preedit type + which the most XIM servers support. Thus, to achieve reasonable + usability, support of "OverTheSpot" preedit type is needed. + + <li>In "OverTheSpot" preedit type, the preedit (preconversion) + string is displayed at the position of the cursor. On the + other hand, it is XIM server's responsibility to display + the preedit string. Thus, it is needed for XIM client (here + XTerm) to inform the XIM server of the cursor position. + And more, to achieve good visual proportion, preedit string + must be written using proper font. Thus, it is XIM client's + responsibility to inform the XIM server of the proper font. + The font must be supplied by "fontset". Fontset is a set of + fonts with charsets which are specified by the current locale. + Since XTerm uses ISO10646 fonts regardless of the current locale, + the fonts for XIM must be prepared separately. It is difficult + to prepare fonts which are similar to XTerm font.

The + basic idea is to use a single set of APIs in the XTerm core, and put + a set of workarounds in a separate file. As you will notice, this + drastically simplifies parts of the code; in particular, the only + remaining ifdefs related to the differences between Xutf8 and legacy + systems are related to the selection provider logic. + + This defines two new files, xutf8.h and xutf8.c, provide some + half-hearted but fully portable emulation for the three Xutf8* + functions that XTerm uses. + + Putting these in a separate file will allow people to experiment with + more complex versions without making the core of XTerm more difficult + to maintain. + + The functionality of the emulation is as follows. + <ul> + <li>Xutf8TextListToTextProperty fully handles XStringstyle and + XUTF8StringStyle.

I see this problem on a SunOS system + running X11R5; the X11R6 servers seem well behaved. + + <li>Implement new escape sequence, private mode 1049, which combines + the switch to/from alternate screen mode with screen clearing and + cursor save/restore. Unlike the existing escape sequence, this + clears the alternate screen when switching to it rather than when + switching to the normal screen, thus retaining the alternate screen + contents for select/paste operations. + + <p>When I implemented the popup menu entry to toggle between the normal + and alternate screens, I considered only pasting from the normal + screen to the alternate; this improvement allows either direction. + + <li>Changed the termcap and terminfo for xterm-xfree86 and xterm-8bit + to use the new 1049 private mode. + + <li>Modify the logic which switches between normal and alternate + screens so that the save/restore cursor operations apply only to the + current screen. That means that applications which use the terminfo + smcur/rmcur or termcap ti/te capabilities will restore the cursor to + the original position on the normal screen rather than to the most + recent place where a save-cursor operation was performed. + + <p>I note that a real VT100 terminal would not behave in this way, + but it is a moot point since the VT100 does not implement alternate + screen, and therefore the save/restore cursor sequence would not be + used in this context.
