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

- * Of these, only '|', '!', '~', '^', '[', and ']' are in question at all.
- *
- * Fortunately too, there is general agreement that codes 0x00 through

- * XXX - how should we distinguish Java from C++?
- * The trick used in a Debian snapshot, of having "extends" or "implements"
- * as tags for Java, doesn't work very well, given that those keywords
- * are often preceded by "class", which flags it as C++.
- *
- * Perhaps we need to be able to say
- *
- * If "class" then
- *
- * if "extends" or "implements" then
- * Java
- * else
- * C++
- * endif
- *
- * Or should we use other keywords, such as "package" or "import"?
- * Unfortunately, Ada95 uses "package", and Modula-3 uses "import",
- * although I infer from the language spec at
- *
- * http://www.research.digital.com/SRC/m3defn/html/m3.html
- *
- * that Modula-3 uses "IMPORT" rather than "import", i.e. it must be
- * in all caps.
- *
- * So, for now, we go with "import". We must put it before the C++
- * stuff, so that we don't misidentify Java as C++. Not using "package"
- * means we won't identify stuff that defines a package but imports
- * nothing; hopefully, very little Java code imports nothing (one of the
- * reasons for doing OO programming is to import as much as possible
- * and write only what you need to, right?).
- *
- * Unfortunately, "import" may cause us to misidentify English text
- * as Java, as it comes after "the" and "The". Perhaps we need a fancier
- * heuristic to identify Java?
