Detailed Description

UTF8 string utilities.

Member Function Documentation

static const char* opencc::UTF8Util::FindNextInline ( const char *  str, const char  ch  )

inlinestatic

Finds a character in the same line.

Parameters

str	The text to be searched in.
ch	The character to find.

Returns

The pointer that points to the found chacter in str or EOL/EOF.

static size_t opencc::UTF8Util::NextCharLengthNoException ( const char *  str )

inlinestatic

Returns the length in byte for the next UTF8 character.

On error returns 0.

static string opencc::UTF8Util::TruncateUTF8 ( const char *  str, size_t  maxByteLength  )

inlinestatic

Truncates a string with a maximal length in byte.

No UTF8 character will be broken.
