A simple library to deal with unicode characters

LANUTF

0.1.6 stable

A library to handle Unicode (UTF-8) in C++.

Whats new in version 0.1.6

• Debugging methods added
  • (UTF8Char) tests passed for all 2097023 unicode characters.

UTF8Char

A UTF8 character is a unicode character encoded in UTF8 format, as “ü” or “😊”.

Important methods:

unsigned int get_charcode();

Returns the unicode scalar value aka charcode of the current character.

void composeUTF8Char(char * source)

Composes a new character from UTF8 encoded source.

void composeUTF8Char(const unsigned int code);

Composes a new character from a unicode scalar value aka charcode.

void copy(UTF8Char & other)

Copies data from another UTF8Char.

char const * c_char() const

Returns the c_char encoded version of the UTF8 char.

UTF8_OctetType const octet() const

Returns the UTF8 octet type of the character.

void clear()

Clears the character.

UTF8CharList

A UTF8 character list is a string of UTF8 encoded characters, as “rené” or “âėīøü”.

Important methods:

size_t size() const

Returns the length of list.

size_t c_str_size() const

Returns the length of a possible C string version of the list.

size_t c_index_at(const size_t index) const

Returns the index of this UTF8Char in a possible C string.

size_t c_index_before(const size_t index) const

Returns the index of the UTF8Char before this in a possible C string.

bool empty() const

Returns true if the list is empty.

void remove(size_t index)

Removes a specified UTF8 character.

char * alloc_c_str() const

Allocates a C string version of the list.

void composeCStr(char * str, size_t size) const

Composes a C string version of the list.

static void free_c_str(char * str)

Frees an allocated C string.

size_t append(const char * str)

Adds characters to the end of the list.

size_t append(const char * str, size_t index)

adds characters to a specified position of the list or to the end if the index isn't valid.

void clear()

Clears the list.

Projets using LanUTF

• LanUI a library to create user interfaces in c++.
  • LanUTF is being user do handle with unicode characters in Freetype2 and text input routines.
