# char2uni(3x)

handling on Unicode, UTF-8 and localized 8 bit encodings libAfterImage/CHAR\_SIZE

## NAME

**char2uni** - handling on Unicode, UTF-8 and localized 8 bit encodings libAfterImage/CHAR\_SIZE

## NAMECHAR\_SIZE

\- Convenient macro so we can transparently determine the number of bytes that character spans. It assumes UTF-8 encoding when I18N is enabled.

## SOURCE

/\* size of the UTF-8 encoded character is based on value of \
  \* the first byte : \*/ #define UTF8\_CHAR\_SIZE(c)   ((((c)&0xC0)==0xC0)? \\\
                              (((c)&0x20)? \\\
                              (((c)&0x10)? \\\
                              (((c)&0x08)? \\\
                              (((c)&0x04)?6:5):4):3):2):1) #ifdef WIN32 #define UNICODE\_CHAR\_SIZE(c)    sizeof(UNICODE\_CHAR) #endif #define CHAR\_SIZE(c)            1
