/*
* T.61 is somewhat braindead; even in the 7-bit space it is not
* completely equivalent to 7-bit US-ASCII. Our definition of the
* character set comes from RFC 1345 with a slightly more readable
* rendition at http://std.dkuug.dk/i18n/charmaps/T.61-8BIT.
*
* Even though '#' and '$' are present in the 7-bit US-ASCII space,
* (x23 and x24, resp.) in T.61 they are mapped to 8-bit characters
* xA6 and xA4.
*
* Also T.61 lacks
* backslash \ (x5C)
* caret ^ (x5E)
* backquote ` (x60)
* left brace { (x7B)
* right brace } (x7D)
* tilde ~ (x7E)
*
* In T.61, the codes xC1 to xCF (excluding xC9, unused) are non-spacing
* accents of some form or another. There are predefined combinations
* for certain characters, but they can also be used arbitrarily. The
* table at dkuug.dk maps these accents to the E000 "private use" range
* of the Unicode space, but I believe they more properly belong in the
* 0300 range (non-spacing accents). The transformation is complicated
* slightly because Unicode wants the non-spacing character to follow
* the base character, while T.61 has the non-spacing character leading.
* Also, T.61 specifically recognizes certain combined pairs as "characters"
* but doesn't specify how to treat unrecognized pairs. This code will
* always attempt to combine pairs when a known Unicode composite exists.
