This function is for use with Mule support. NAME is a symbol, the name by which the character set is normally referred. DOC-STRING is a string describing the character set. PROPS is a property list, describing the specific nature of the character set. Recognized properties are: `short-name' Short version of the charset name (ex: Latin-1) `long-name' Long version of the charset name (ex: ISO8859-1 (Latin-1)) `registries' A vector of possible XLFD REGISTRY-ENCODING combinations for this character set. Note that this is not a regular expression. `dimension' Number of octets used to index a character in this charset. Either 1 or 2. Defaults to 1. `columns' Number of columns used to display a character in this charset. Only used in TTY mode. (Under X, the actual width of a character can be derived from the font used to display the characters.) If unspecified, defaults to the dimension (this is almost always the correct value). `chars' Number of characters in each dimension (94 or 96). Defaults to 94. Note that if the dimension is 2, the character set thus described is 94x94 or 96x96. `final' Final byte of ISO 2022 escape sequence. Must be supplied. Each combination of (DIMENSION, CHARS) defines a separate namespace for final bytes. Note that ISO 2022 restricts the final byte to the range 0x30 - 0x7E if dimension == 1, and 0x30 - 0x5F if dimension == 2. Note also that final bytes in the range 0x30 - 0x3F are reserved for user-defined (not official) character sets. `graphic' 0 (use left half of font on output) or 1 (use right half of font on output). Defaults to 0. For example, for a font whose registry is ISO8859-1, the left half (octets 0x20 - 0x7F) is the `ascii' character set, while the right half (octets 0xA0 - 0xFF) is the `latin-1' character set. With `graphic' set to 0, the octets will have their high bit cleared; with it set to 1, the octets will have their high bit set. `direction' `l2r' (left-to-right) or `r2l' (right-to-left). Defaults to `l2r'. `ccl-program' A compiled CCL program used to convert a character in this charset into an index into the font. This is in addition to the `graphic' property. The CCL program is passed the octets of the character, with the high bit cleared and set depending upon whether the value of the `graphic' property is 0 or 1. `encode-as-utf-8' If non-nil, the charset will be written out using the UTF-8 escape syntax in ISO 2022-oriented coding systems.

Normally the strings are checked to make sure they contain no XLFD wild cards and that they contain at least one hyphen; the only context in which one might want not to do this is in order to use a font which doesn't have a full XLFD--and thus, an effective CHARSET_REGISTRY-CHARSET_ENCODING of ""--to display ASCII. We recommend strongly that you specify a full XLFD, since this makes multilingual and variant font handling work much better. To get the full XLFD of any font, start xfd with the short name as the pattern argument: xfd -fn 8x16kana and use the text that appears at the top of the window. */ (charset, registries, force)) { int i; charset = Fget_charset (charset); CHECK_VECTOR (registries); for (i = 0; i < XVECTOR_LENGTH(registries); ++i) { CHECK_STRING (XVECTOR_DATA(registries)[i]); if (!NILP(force)) { continue; } if (NULL == qxestrchr(XSTRING_DATA(XVECTOR_DATA(registries)[i]), '-')) { invalid_argument("Not an X11 REGISTRY-ENCODING combination", XVECTOR_DATA(registries)[i]); } if (qxestrchr(XSTRING_DATA(XVECTOR_DATA(registries)[i]), '*') || qxestrchr(XSTRING_DATA(XVECTOR_DATA(registries)[i]), '?')) { invalid_argument ("XLFD wildcards not allowed in charset-registries", XVECTOR_DATA(registries)[i]); } } set_charset_registries(charset, registries); return Qnil; } DEFUN ("charsets-in-region", Fcharsets_in_region, 2, 3, 0, /* Return a list of the charsets in the region between START and END.
