56 * FT_WinFNT_ID_XXX | |
57 * | |
58 * @description: | |
59 * A list of valid values for the `charset' byte in | |
60 * @FT_WinFNT_HeaderRec. Exact mapping tables for the various cpXXXX | |
61 * encodings (except for cp1361) can be found at | |
62 * ftp://ftp.unicode.org/public in the MAPPINGS/VENDORS/MICSFT/WINDOWS | |
63 * subdirectory. cp1361 is roughly a superset of | |
64 * MAPPINGS/OBSOLETE/EASTASIA/KSC/JOHAB.TXT. | |
65 * | |
66 * @values: | |
67 * FT_WinFNT_ID_DEFAULT :: | |
68 * This is used for font enumeration and font creation as a | |
69 * `don't care' value. Valid font files don't contain this value. | |
70 * When querying for information about the character set of the font | |
71 * that is currently selected into a specified device context, this | |
72 * return value (of the related Windows API) simply denotes failure. | |
73 * | |
74 * FT_WinFNT_ID_SYMBOL :: | |
75 * There is no known mapping table available. | |
76 * | |
77 * FT_WinFNT_ID_MAC :: | |
78 * Mac Roman encoding. | |
79 * | |
80 * FT_WinFNT_ID_OEM :: | |
81 * From Michael Pöttgen <michael@poettgen.de>: | |
82 * | |
83 * The `Windows Font Mapping' article says that FT_WinFNT_ID_OEM | |
84 * is used for the charset of vector fonts, like `modern.fon', | |
85 * `roman.fon', and `script.fon' on Windows. | |
86 * | |
87 * The `CreateFont' documentation says: The FT_WinFNT_ID_OEM value | |
88 * specifies a character set that is operating-system dependent. | |
89 * | |
90 * The `IFIMETRICS' documentation from the `Windows Driver | |
91 * Development Kit' says: This font supports an OEM-specific | |
92 * character set. The OEM character set is system dependent. | |
93 * | |
94 * In general OEM, as opposed to ANSI (i.e., cp1252), denotes the | |
95 * second default codepage that most international versions of | |
96 * Windows have. It is one of the OEM codepages from | |
97 * | |
98 * http://www.microsoft.com/globaldev/reference/cphome.mspx, | |
99 * | |
100 * and is used for the `DOS boxes', to support legacy applications. | |
101 * A German Windows version for example usually uses ANSI codepage | |
102 * 1252 and OEM codepage 850. | |
103 * | |
104 * FT_WinFNT_ID_CP874 :: | |
105 * A superset of Thai TIS 620 and ISO 8859-11. | |
106 * | |
107 * FT_WinFNT_ID_CP932 :: | |
108 * A superset of Japanese Shift-JIS (with minor deviations). | |
109 * | |
110 * FT_WinFNT_ID_CP936 :: | |
111 * A superset of simplified Chinese GB 2312-1980 (with different | |
112 * ordering and minor deviations). | |
113 * | |
114 * FT_WinFNT_ID_CP949 :: | |
115 * A superset of Korean Hangul KS~C 5601-1987 (with different | |
116 * ordering and minor deviations). | |
117 * | |
118 * FT_WinFNT_ID_CP950 :: | |
119 * A superset of traditional Chinese Big~5 ETen (with different | |
120 * ordering and minor deviations). | |
121 * | |
122 * FT_WinFNT_ID_CP1250 :: | |
123 * A superset of East European ISO 8859-2 (with slightly different | |
124 * ordering). | |
125 * | |
126 * FT_WinFNT_ID_CP1251 :: | |
127 * A superset of Russian ISO 8859-5 (with different ordering). | |
128 * | |
129 * FT_WinFNT_ID_CP1252 :: | |
130 * ANSI encoding. A superset of ISO 8859-1. | |
131 * | |
132 * FT_WinFNT_ID_CP1253 :: | |
133 * A superset of Greek ISO 8859-7 (with minor modifications). | |
134 * | |
135 * FT_WinFNT_ID_CP1254 :: | |
136 * A superset of Turkish ISO 8859-9. | |
137 * | |
138 * FT_WinFNT_ID_CP1255 :: | |
139 * A superset of Hebrew ISO 8859-8 (with some modifications). | |
140 * | |
141 * FT_WinFNT_ID_CP1256 :: | |
142 * A superset of Arabic ISO 8859-6 (with different ordering). | |
143 * | |
144 * FT_WinFNT_ID_CP1257 :: | |
145 * A superset of Baltic ISO 8859-13 (with some deviations). | |
146 * | |
147 * FT_WinFNT_ID_CP1258 :: | |
148 * For Vietnamese. This encoding doesn't cover all necessary | |
149 * characters. | |
150 * | |
151 * FT_WinFNT_ID_CP1361 :: | |
152 * Korean (Johab). | |
