Even with Unicode. There is a problem. 1347dnl 1348dnl While most of the VT100 graphics characters were incorporated into Unicode, 1349dnl all of those were combined into a page of useful graphics characters. 1350dnl 1351dnl So far, so good. 1352dnl 1353dnl However, while they are useful, there are other considerations. CJK 1354dnl is (because of poor device resolution) often rendered as double-width 1355dnl characters. So... for these generally-useful characters, what should 1356dnl be the width (to make them consistent with adjacent characters)? 1357dnl 1358dnl The obvious choice would have been to make this locale-dependent, and use 1359dnl wcwidth() to tell applications what the actual width is. That was too 1360dnl obvious. Instead, we have a slew of "ambiguous-width" characters. 1361dnl See for example 1362dnl http://www.unicode.org/reports/tr11/tr11-29.html 1363dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html 1364dnl 1365dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists 1366dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For 1367dnl instance, it lists half (44/96) of the Latin-1 characters as 1368dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous. 1369dnl 1370dnl What this means for the implementor is that on some systems wcwidth() can 1371dnl give bad advice. On Solaris, some of the ambiguous widths are returned as 1372dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing 1373dnl characters). These do not necessarily match the behavior of the terminal 1374dnl emulator. xterm, for instance, does an optional startup check to find if 1375dnl this problem (or similar) exists with the system's locale tables, rejecting 1376dnl them if they are too unreliable. 1377AC_DEFUN([CF_CHECK_WCWIDTH_GRAPHICS],[ 1378AC_CACHE_CHECK(if wcwidth agrees graphics are single-width, cf_cv_wcwidth_graphics,[ 1379cat >conftest.in <<CF_EOF 1380- VT100 symbols 13810x250c upper left corner 13820x2514 lower left corner 13830x2510 upper right corner 13840x2518 lower right corner 13850x251c tee pointing left 13860x2524 tee pointing right 13870x2534 tee pointing up 13880x252c tee pointing down 13890x2500 horizontal line 13900x2502 vertical line 13910x253c large plus or crossover 13920x23ba scan line 1 13930x23bd scan line 9 13940x25c6 diamond 13950x2592 checker board (stipple) 13960x00b0 degree symbol 13970x00b1 plus/minus 13980x00b7 bullet 1399- Teletype 5410v1 symbols 14000x2190 arrow pointing left 14010x2192 arrow pointing right 14020x2193 arrow pointing down 14030x2191 arrow pointing up 14040x2592 board of squares 14050x2603 lantern symbol 14060x25ae solid square block 1407- these defaults were invented for ncurses 14080x23bb scan line 3 14090x23bc scan line 7 14100x2264 less-than-or-equal-to 14110x2265 greater-than-or-equal-to 14120x03c0 greek pi 14130x2260 not-equal 14140x00a3 pound-sterling symbol 1415- thick-line-drawing 14160x250f upper left corner 14170x2517 lower left corner 14180x2513 upper right corner 14190x251b lower right corner 14200x2523 tee pointing left 14210x252b tee pointing right 14220x253b tee pointing up 14230x2533 tee pointing down 14240x2501 horizontal line 14250x2503 vertical line 14260x254b large plus or crossover 1427- double-line-drawing 14280x2554 upper left corner 14290x255a lower left corner 14300x2557 upper right corner 14310x255d lower right corner 14320x2563 tee pointing left 14330x2560 tee pointing right 14340x2569 tee pointing up 14350x2566 tee pointing down 14360x2550 horizontal line 14370x2551 vertical line 14380x256c large plus or crossover 1439CF_EOF 1440AC_TRY_RUN([ 1441#include <locale.h> 1442#include <stdio.h> 1443#include <wchar.h> 1444 1445#define MY_LEN 80 1446 1447int 1448main(void) 1449{ 1450 FILE *fp; 1451 int value; 1452 char buffer[MY_LEN + 1]; 1453 char notes[MY_LEN + 1]; 1454 int totals = 0; 1455 int passed = 0; 1456 1457 if (setlocale(LC_ALL, "en_US.UTF8") || 1458 setlocale(LC_ALL, "en_US.UTF-8") || 1459 setlocale(LC_ALL, "en_US.utf8") || 1460 setlocale(LC_ALL, "en_US.utf-8")) { 1461 if ((fp = fopen("conftest.in", "r")) != 0) { 1462 while (fgets(buffer, MY_LEN, fp) != 0) { 1463 if (*buffer == '-') { 1464 fprintf(stderr, "\\t%s", buffer); 1465 } else if (sscanf(buffer, "%x %s", &value, notes) == 2) { 1466 ++totals; 1467 if (wcwidth(value) == 1) 1468 ++passed; 1469 fprintf(stderr, "%d\\t%s", wcwidth(value), buffer); 1470 } else { 1471 fprintf(stderr, "?\\t%s", buffer); 1472 } 1473 } 1474 } 1475 } 1476 fprintf(stderr, "%d/%d passed wcwidth/graphics check\\n", passed, totals); 1477 return (totals == passed) ? 0 : 1; 1478} 1479], 1480[cf_cv_wcwidth_graphics=yes], 1481[cf_cv_wcwidth_graphics=no], 1482[cf_cv_wcwidth_graphics=unknown]) 1483]) 1484])dnl 1485dnl --------------------------------------------------------------------------- 1486dnl CF_CLANG_COMPILER version: 8 updated: 2021/01/01 13:31:04 1487dnl ----------------- 1488dnl Check if the given compiler is really clang. clang's C driver defines 1489dnl __GNUC__ (fooling the configure script into setting $GCC to yes) but does 1490dnl not ignore some gcc options. 1491dnl 1492dnl This macro should be run "soon" after AC_PROG_CC or AC_PROG_CPLUSPLUS, to 1493dnl ensure that it is not mistaken for gcc/g++.
