- * VTE Character Sets
- * These are predefined charactersets that can be loaded into GL and GR. By
- * default we use unicode_lower and unicode_upper, that is, both sets have the
- * exact unicode mapping. unicode_lower is effectively ASCII and unicode_upper
- * as defined by the unicode standard (I guess, ISO 8859-1).
- * Several other character sets are defined here. However, all of them are
- * limited to the 96 character space of GL or GR. Everything beyond GR (which
- * was not supported by the classic VTs by DEC but is available in VT emulators
- * that support unicode/UTF8) is always mapped to unicode and cannot be changed
- * by these character sets. Even mapping GL and GR is only available for
- * backwards compatibility as new applications can use the Unicode functionality
- * of the VTE.
- *
- * Moreover, mapping GR is almost unnecessary to support. In fact, Unicode UTF-8
- * support in VTE works by reading every incoming data as UTF-8 stream. This
- * maps GL/ASCII to ASCII, as UTF-8 is backwards compatible to ASCII, however,
- * everything that has the 8th bit set is a >=2-byte haracter in UTF-8. That is,
- * this is in no way backwards compatible to >=VT220 8bit support. Therefore, if
- * someone maps a character set into GR and wants to use them with this VTE,
- * then they must already send UTF-8 characters to use GR (all GR characters are
- * 8-bits). Hence, they can easily also send the correct UTF-8 character for the
- * unicode mapping.
- * The only advantage is that most characters in many sets are 3-byte UTF-8
- * characters and by mapping the set into GR/GL you can use 2 or 1 byte UTF-8
- * characters which saves bandwidth.
- * Another reason is, if you have older applications that use the VT220 8-bit
- * support and you put a ASCII/8bit-extension to UTF-8 converter in between, you
- * need these mappings to have the application behave correctly if it uses GL/GR
- * mappings extensively.
- *
- * Anyway, we support GL/GR mappings so here are the most commonly used maps as
- * defined by Unicode-standard, DEC-private maps and other famous charmaps.
- *
- * Characters 1-32 are always the control characters (part of CL) and cannot be
- * mapped. Characters 34-127 (94 characters) are part of GL and can be mapped.
- * Characters 33 and 128 are not part of GL and always mapped by the VTE.
- * However, for GR they can be mapped differently (96 chars) so we have to
- * include them. The mapper has to take care not to use them in GL.
