142: * This table reflects a particular philosophy about what constitutes
143: * "text," and there is room for disagreement about it.
144: *
145: * Version 3.31 of the file command considered a file to be ASCII if
146: * each of its characters was approved by either the isascii() or
147: * isalpha() function. On most systems, this would mean that any
148: * file consisting only of characters in the range 0x00 ... 0x7F
149: * would be called ASCII text, but many systems might reasonably
150: * consider some characters outside this range to be alphabetic,
151: * so the file command would call such characters ASCII. It might
152: * have been more accurate to call this "considered textual on the
153: * local system" than "ASCII."
154: *
155: * It considered a file to be "International language text" if each
156: * of its characters was either an ASCII printing character (according
157: * to the real ASCII standard, not the above test), a character in
158: * the range 0x80 ... 0xFF, or one of the following control characters:
159: * backspace, tab, line feed, vertical tab, form feed, carriage return,
160: * escape. No attempt was made to determine the language in which files
161: * of this type were written.
162: *
163: *
164: * The table below considers a file to be ASCII if all of its characters
165: * are either ASCII printing characters (again, according to the X3.4
166: * standard, not isascii()) or any of the following controls: bell,
167: * backspace, tab, line feed, form feed, carriage return, esc, nextline.
168: *
169: * I include bell because some programs (particularly shell scripts)
170: * use it literally, even though it is rare in normal text. I exclude
171: * vertical tab because it never seems to be used in real text. I also
172: * include, with hesitation, the X3.64/ECMA-43 control nextline (0x85),
173: * because that's what the dd EBCDIC->ASCII table maps the EBCDIC newline
174: * character to. It might be more appropriate to include it in the 8859
175: * set instead of the ASCII set, but it's got to be included in *something*
176: * we recognize or EBCDIC files aren't going to be considered textual.
177: * Some old Unix source files use SO/SI (^N/^O) to shift between Greek
178: * and Latin characters, so these should possibly be allowed. But they
179: * make a real mess on VT100-style displays if they're not paired properly,
180: * so we are probably better off not calling them text.
181: *
182: * A file is considered to be ISO-8859 text if its characters are all
183: * either ASCII, according to the above definition, or printing characters
184: * from the ISO-8859 8-bit extension, characters 0xA0 ... 0xFF.
185: *
186: * Finally, a file is considered to be international text from some other
187: * character code if its characters are all either ISO-8859 (according to
188: * the above definition) or characters in the range 0x80 ... 0x9F, which
189: * ISO-8859 considers to be control characters but the IBM PC and Macintosh
190: * consider to be printing characters.
