BloombergLP::bdlde::Utf8Util::isValid

Synopses

Declared in <bdlde_utf8util.h>

Return true if the specified string contains valid UTF-8, and false otherwise. string need not be null-terminated and can contain embedded null bytes.

static
bool
isValid(std::string_view const& string);

Return true if the specified string contains valid UTF-8, and false otherwise. string is necessarily null-terminated, so it cannot contain embedded null bytes.

static
bool
isValid(char const* string);

» more...

Return true if the specified string having the specified length (in bytes) contains valid UTF-8, and false otherwise. string need not be null-terminated and can contain embedded null bytes, and string may be null if 0 == length (see {Empty Input Strings}).

static
bool
isValid(
    char const* string,
    size_type length);

Return true if the specified string contains only valid UTF-8 characters, and false otherwise. If string contains invalid UTF-8, load into the specified invalidString the address of the byte after the last valid code point traversed; invalidString is unaffected if string contains only valid UTF-8. string need not be null-terminated and can contain embedded null bytes.

isValid(
    char const** invalidString,

Return true if the specified string contains valid UTF-8, and false otherwise. If string contains invalid UTF-8, load into the specified invalidString the address of the beginning of the first invalid UTF-8 sequence encountered; invalidString is unaffected if string contains only valid UTF-8. string is necessarily null-terminated, so it cannot contain embedded null bytes.
