1 Tex with Unicode Characters 7/10/18 Presented by: Yuefei Xiang

2 Agenda ASCII Code Unicode Unicode in Tex Old Style Encoding -Inputenc, -ucs Morden Encoding -XeTeX -LuaTeX Unicode bi-direction in Tex -Emacs-AucTeX -XSL-FO!2

3 ASCII Code Basic ASCII(0-127) Input just by keyboard!3

$\usepackage[t1]{fontenc} \charnumber Eg.$

4 Cork Encoding Cork encoding(0-256) \usepackage[t1]{fontenc} \charnumber Eg. -> \char34 Č -> \char268!4

5 Unicode 0-32, control codes backward compatible ASCII codes Latin-1 Latin extended Greek extended, Cyrillic!5

6 Unicode in TeX

7 Unicode in TeX None-math mode symbols:!7

8 Unicode in TeX He said Hello to Dan -> He said Hello to Dan.!8

9 Unicode in TeX He said Hello to Dan -> He said Hello to Dan. He said ''Hello'' to Dan -> He said Hello to Dan!9

10 Unicode in TeX He said Hello to Dan -> He said Hello to Dan. He said ''Hello'' to Dan -> He said Hello to Dan He said `` Hello ' ' to Dan -> He said Hello to Dan.!10

11 Unicode in TeX math mode symbols:!11

12 Unicode in TeX math mode symbols: $abc$ Means abc is in math mode eg. -> $\sum$!12

13 Unicode Latin, Greek Various encoding schema GBK(Chinese) Kanji(Japanese) KOI8-RU(Russian) Only small part of characters are supported by original Donald Knuth's TeX How to deal with other characters?!13

14 Unicode in TeX old-style old-style Modern Tex (DVI) pdftex (PDF) LuaTex (PDF) Modern XeTex (XDV)!14

15 Old Style Inputenc(utf8) This package is of vital importance if you use non-ascii characters in your document. For example, if you type the word Ángela, the Á character will not appear correctly in the output. To solve this problem, use: Universal Code Character Set(utf8x) More mathematical symbols are supported, for example,,,,, and several kinds of arrows. Double-struck letters (A, B, etc.) are now typeset using \mathbb instead of \mathbbm. The handling of small greek letters in math mode has been improved.!15

16 Old Style Universal Code Character Set(utf8x)!16

17 XeTex Adaptation for Mac OS X Allowed to use UTF-8 and UTF-16(with UTF-16 Byte Order Mark found) Convert automatically Read UTF-8 input files Byte sequences Unicode Without addition TeX macros eg. Inputenc package!17

18 XeTex Mac OS Roman!18

19 XeTex \XeTeXinputencoding "charset-name" "mac" (Mac OS Roman), "cp1252" (Windows codepage 1252, Western European), "shift-jis" (e.g., for Japanese)!19

20 XeTex- Hyphenation support The hyphenation tables in XeTeX have been extended to support 16-bit Unicode characters. Hyphenation patterns using Devanagari letters!20

21 LuaTex- callbacks Common used callbacks!21

22 LuaTex- callbacks mapping a byte to its numerical representation in Unicode u is 253 in Latin-3 turning that representation into unicode byte 0x016D (365) in Unicode!22

23 Unicode bi-direction in Tex Emacs- AUCTex Texmaker/TexStudio(support has been removed, not enough stable) XSL-FO!23

24 Emacs Emacs(Editing macros) editing environment/text work environment. GNU Emacs created by Richard Stallman AucTEX: collection of Emacs functions supporting modes for editing Tex documents!24

25 AucTEX Set buffer-local variables bidi-display-reordering (controls whether text in the buffer is reordered for display) Value = non-nil(right-ti-left) Default Value = t(left-to-right) bidi-paragraph-start-re & bidi-paragraph-separate-reto (truncate paragraphs) Value = ^ bidi-paragraph-direction (dynamic determination of the base direction) Value = right-to-left/left-to-right Default Value = non-nil(disable the dynamic determination of the base direction)!25

26 AucTEX Set formatting characters RIGHT-TO-LEFT MARK / rlm forces the right-to-left direction on the following paragraph LEFT-TO-RIGHT MARK / lrm forces the left-to-right direction on the following paragraph!26

27 XSL-FO!27

28 XSL-FO xml-like syntax writing-mode attribute: lr-tb: for left-to-right, top-to-bottom (the default value), suitable for languages such as English, Polish rl-tb: for right-to-left, top-to-bottom, suitable for languages such as Hebrew and Arabic tb-rl: for top-to-bottom, right-to-left, suitable for traditional Japanese lr-alternating-rl-bt, lr-inverting-rl-bt!28
