Features
{ANY}
decode (utf8_string: STRING, unicode_string: UNICODE_STRING)
effective procedure
{ANY}
top
Decode the utf8_string and append it in unicode_string.
After this call the first_error attribute may be non Void to explain the error encountered during the utf8_string decoding. In case of error, the first_error_index is also used to indicate the position of the first error into the original utf8_string, first_error_character indicate the position of the first error character added in unicode_string.
require
  • utf8_string /= Void
  • unicode_string /= Void
first_error: STRING
writable attribute
{ANY}
top
When first_error is not Void, this means that an error has occured during the last decode call.
In such a situation, first_error is an explanation of the error.
first_error_index: INTEGER_32
writable attribute
{ANY}
top
Meaningful only when first_error is not Void to indicate the position of the error in utf8_string (see decode).
first_error_character: INTEGER_32
writable attribute
{ANY}
top
Meaningful only when first_error is not Void to indicate the position of the first error character added to unicode_string (see decode).
