Why a spelling is not a literal.

Variants

NotALiteral

The spelling is not a character constant or a string literal at all, which the caller cannot reach from a token the scanner produced.

Empty

'', which has no character in it to have a value.

TooLong

More characters than the type has room for, in the one encoding where that is an error rather than a warning.

NoHexDigits

\x with no hexadecimal digit after it.

IncompleteUcn

A universal character name that stops before its digits are done.

InvalidUcn

A universal character name that may not name what it names: a character in the basic character set, a surrogate, or a code point past the end of Unicode.

NamedUcn

\N{NAME}, which gcc 13.3 has in C++23 and in no C dialect.

InvalidUtf8

A byte in the source that is not part of a character, in a literal whose encoding has to know what the characters are.

PrefixNotInDialect

An encoding prefix the dialect does not have.

MixedEncodings

A run of adjacent string literals written with two different prefixes, which neither compiler has an answer for.
