For example, suppose -you have a ^{Norwegian keyboard} containing the letter {\tt\ae}, which -^^{Scandinavian letters} ^^{foreign languages} -comes in as code~241 (say). Your local format package should define -|\catcode`|{\tt\ae}|=11|; then you could have control sequences like -|\s|{\tt\ae}|rtrykk|. Your \TeX\ input files could be made readable by -American installations of \TeX\ that don't have your keyboard, by -substituting |^^f1| for character~241. \ (For example, the stated control -sequence would appear as |\s^^f1rtrykk| in the file; your American -friends should also be provided with the format that you used, with its -|\catcode`^^f1=11|.) \ Of course you should also arrange your fonts -so that \TeX's character 241 will print as {\ae}; and you should -change \TeX's hyphenation algorithm so that it will do correct -Norwegian hyphenation. The main point is that such changes are not -extremely difficult; nothing in the design of \TeX\ limits it to the -American alphabet. Fine printing is obtained by fine tuning to the -language or languages being used. -^^{keyboards, non-ASCII} - -\ddanger European languages can also be accommodated effectively with -only a limited character set. -For example, let's consider Norwegian again, but suppose that\parfillskip=0pt - -\noindent [Now continue with the text on line 11 of page 46.] - -\bugonpage A47, lines 9--21 (9/23/89) - -\ddanger If \TeX\ sees a superscript character (category 7) in any state, -and if that character is followed by another identical character, and if -those two equal characters are followed by a character of code -$c<128$, then they -are deleted and 64 is added~to or subtracted from the code~$c$. -\ (Thus, |^^A| is -replaced by a single character whose code is~1, etc., as explained earlier.) \ -However, if the two superscript characters are immediately followed by two -of the lowercase hexadecimal digits |0123456789abcdef|, the -four-character sequence is replaced by a single character having the -specified hexadecimal code. -The replacement is carried out also if such a trio or quartet of -characters is encountered during steps (b) or~(c) of the control-sequence-name -scanning procedure described above.

But infinite tolerance is a bad idea, because -\TeX\ doesn't distinguish between terribly bad and preposterously -horrible lines. Indeed, a tolerance of 10000 encourages \TeX\ to -concentrate all the badness in one place, making one truly unsightly -line instead of two moderately bad ones, because a single -``write-off'' produces fewest total demerits according to the rules. -There's a much better way to get the desired effect: \TeX\ has a -parameter called ^|\emergencystretch| that is added to the assumed -stretchability of every line when badness and demerits are computed, -in cases where overfull boxes are otherwise unavoidable. If -|\emergencystretch| is positive, \TeX\ will make a third pass over a -paragraph before choosing the line breaks, when the first passes did -not find a way to satisfy the ^|\pretolerance| and ^|\tolerance|. -The effect of\/ |\emergencystretch| is to scale down the badnesses so -that large infinities are distinguishable from smaller ones.

You can insert -the whatsit yourself (even in restricted horizontal mode) by saying -^|\setlanguage|\; this changes the current language but it -does not change |\language|. - -\endgroup - -\bugonpage A459, right column (9/23/89) - -\eightpoint\indent\hbox to0pt{\hss\lower1pt\hbox{*}}% -|\badness|, 214, {\it229}, 271. - -\bugonpage A461, right column (9/23/89) - -\eightpoint -caron, {\sl see\/} h\'a\v cek. - -\bugonpage A464, line 10 (5/15/89) - -\eightpoint -displays, 87, 103, {\it139--145}, {\it166--167}, - -\bugonpage A464, right column (9/23/89) - -\eightpoint\indent\hbox to0pt{\hss\lower1pt\hbox{*}}% -|\emergencystretch|, $\underline{107}$, 274. - -\bugonpage A465, left column (9/23/89) - -\eightpoint\indent\hbox to0pt{\hss\lower1pt\hbox{*}}% -|\errorcontextlines|, $\underline{34}$, 273, {\it348}. - -\bugonpage A466, entry for `fractions' (9/23/89) - -\eightpoint[Add page 332 to this entry.] - -\bugonpage A466, entry for `French'' (9/23/89) - -\eightpoint[Add page 455 to this entry.] - -\bugonpage A467, entry for `hexadecimal' (9/23/89) - -\eightpoint[Add pages 45, 47--48 to this entry.] - -\bugonpage A467, right column (9/23/89) - -\eightpoint\indent\hbox to0pt{\hss\lower1pt\hbox{*}}% -|\holdinginserts|, $\underline{125}$, 273, 400. - -\bugonpage A467, bottom line (9/23/89) - -\eightpoint\indent\hbox to0pt{\hss\lower1pt\hbox{*}}% -|\hyphenation|, 277, {\it419}, $\underline{452}$--$\underline{453}$, 455. - -\bugonpage A468, right column (9/23/89) - -\eightpoint -infinite badness, 97, 107, 111, 229, 317. - -\bugonpage A468, right column (9/23/89) - -\eightpoint\indent\hbox to0pt{\hss\lower1pt\hbox{*}}% -|\inputlineno|, 214, 271. - -\bugonpage A469, entry for kerns (9/23/89) - -\eightpoint[Add pages 286 and 444 to this entry.] - -\bugonpage A469, left column (9/23/89) - -\eightpoint\indent\hbox to0pt{\hss\lower1pt\hbox{*}}% -|\language| (hyphenation method), 273, $\underline{455}$. - -\bugonpage A469, right column (9/23/89) - -\eightpoint\indent\hbox to0pt{\hss\lower1pt\hbox{*}}% -|\lefthyphenmin|, 273, {\it364}, $\underline{454}$. - -\bugonpage A470, entry for ligatures (9/23/89) - -\eightpoint[Add pages 286 and 444 to this entry.] - -\bugonpage A472, left column (9/23/89) - -\eightpoint\indent\hbox to0pt{\hss\lower1pt\hbox{*}}% -|\noboundary|, 283, $\underline{286}$, 290. - -\bugonpage A473, right column (9/23/89) - -\eightpoint -overfull boxes, 27--30, 94, 229, 238,\par -\indent\qquad 302--303, 307, 400.\par -\indent\quad avoiding, 107. - -\bugonpage A474, left column (9/23/89) - -\eightpoint\indent\hbox to0pt{\hss\lower1pt\hbox{*}}% -|\patterns|, 277, $\underline{453}$, 455. - -\bugonpage A476, left column (9/23/89) - -\eightpoint\indent\hbox to0pt{\hss\lower1pt\hbox{*}}% -|\righthyphenmin|, 273, {\it364}, $\underline{454}$. - -\bugonpage A476, right column (9/23/89) - -\eightpoint\indent\hbox to0pt{\hss\lower1pt\hbox{*}}% -|\setlanguage|, 287, $\underline{455}$. - -\bugonpage A476, right column (9/23/89) - -\eightpoint\indent\hbox to0pt{\hss\lower1pt\hbox{*}}% -|\showboxbreadth|, 273, $\underline{302}$, 303, {\it348}.\par -\indent\hbox to0pt{\hss\lower1pt\hbox{*}}% -|\showboxdepth|, 79, 273, $\underline{302}$, 303, {\it348}. - -\bugonpage A479, left column (9/23/89) - -\eightpoint\indent\hbox to0pt{\hss\lower1pt\hbox{*}}% -|\tolerance|, {\it29--30}, 91, 94, $\underline{96}$, 107, 272,\par -\indent\qquad{\it317}, {\it333}, {\it342}, {\it348}, {\it364}, {\it451}. - -\bugonpage A481, right column, last six entries (9/23/89) - -\def\frac#1/#2{\leavevmode\kern.1em - \raise.5ex\hbox{\the\scriptfont0 #1}\kern-.1em - /\kern-.15em\lower.25ex\hbox{\the\scriptfont0 #2}}% -\eightpoint -\frac1/2, 67, 332.\par -1/2, in unslashed form, 141, 186.\par -\<4-bit number>, $\underline{271}$.\par -\<8-bit number>, $\underline{271}$, 276--278.\par -\<15-bit number>, $\underline{271}$, 277, 289, 291.\par -\<27-bit number>, $\underline{271}$, 289, 291.\par - -\bugonpage A483, lines 15 and 21 (9/23/89) - -\noindent[Delete these two lines, as TUG's address is no longer c/o AMS.] - - % volume B -\hsize=35pc -\def\\#1{\hbox{\it#1\/\kern.05em}} % italic type for identifiers -\def\to{\mathrel{.\,.}} % double dot, used only in math mode - -\bugonpage Bvii, top two lines (4/21/89) - -{\hsize=29pc -\tenpoint\noindent -{\it {\sltt WEB} documentation for four utility programs that are -often used in conjunction with \TeX: {\sltt POOLtype}, {\sltt TFtoPL}, -{\sltt PLtoTF}, and {\sltt DVItype}.} -\par} - -\bugonpage B2, line 32 (6/20/89) - -\ninepoint\noindent\hskip10pt -{\bf define} $\\{banner}\equiv\hbox{\tt\char'23}$% -{\tt This\]is\]TeX,\]Version\]2.991\char'23}\quad -$\{\,$printed when \TeX\ starts$\,\}$ - -\bugonpage B118, lines 2--4 (3/2/89) - -\ninepoint\noindent\hskip10pt -{\bf begin if\/} $\\{cur\_level}>\\{level\_one}$ {\bf then}\par -\noindent\hskip20pt{\bf begin} \\{check\_full\_save\_stack};
