unicode_set_error_mode — Set the error mode for strings conversions
说明
This function sets the error mode for string conversions between different encodings. An error can occur during conversion when an illegal character is encountered or if a character cannot be represented into the new encoding. By default, when an error is encountered, the conversion stops.
参数
- direction
-
The direction sets the conversion direction to which the error mode will apply. This can either be FROM_UNICODE, which will set the error mode for conversions from a unicode string to a binary string or TO_UNICODE, which will set the error mode for conversions from a binary string to a unicode string.
- mode
-
mode determines how the conversion errors are handled. It should be one of the following constants:
Available modes Mode Description U_CONV_ERROR_STOP Stop the conversion. This is the default mode. U_CONV_ERROR_SKIP Skip the character. U_CONV_ERROR_SUBST Substitute the character. The substituting character can be set with unicode_set_subst_char(). U_CONV_ERROR_ESCAPE_UNICODE Escape the faulty bytes and represent them in the Unicode character format. U_CONV_ERROR_ESCAPE_ICU Escape the faulty bytes and represent them in the ICU character format. U_CONV_ERROR_ESCAPE_JAVA Escape the faulty bytes and print them in the Java character format. U_CONV_ERROR_ESCAPE_XML_DEC Escape the faulty bytes and represent them in decimal format. U_CONV_ERROR_ESCAPE_XML_HEX Escape the faulty bytes and represent them in hexadecimal format.
返回值
如果成功则返回 TRUE，失败则返回 FALSE。
错误／异常
Emits a E_WARNING level error if the direction or the mode are invalid.
