Representing Non-English Characters

Contributions with names that employ diacritic marks (accents, umlauts, etc.) are advised not to use special control codes (e.g., 8-bit ASCII) to to represent these characters, as they frequently do not survive transmission via e-mail.

Use of the scheme below will ensure that any special characters required in your item/report will survive transmission via e-mail. The scheme is that used by the TeX typesetting system. The examples below can be extrapolated to other letters as necessary. Use of the curly brackets in some cases as indicated below is important.

Other helpful TeX commands. Exponents are denoted by a caret (^), with whatever is to be raised placed inside curly brackets; thus, 10 to the 25th power would be written 10^{25}. Likewise, subscripts are denoted by an underline (_). (Simply give plus-or-minus as "+/-".) Also, use \it for italicizing, \bf for boldface type, and \rm for regular Roman type. One can use curly brackets to encompass a single word/phrase in italics or boldface, as {\it Ap.J.} {\bf 23}, 422.

For details on other specialist symbols that your item/report may require you are referred to textbooks on TeX. E.g., The TeXbook by D. E. Knuth, 1986 (ISBN 0-201-13448-9).
