DecodeLastRune (FUN) ¶ FUNCTION DecodeLastRune : RUNE Unpacks the last UTF-8 encoding in pbyData and returns the rune and its position ( udiIndex ) and length ( udiLength ) in bytes. If pbyData is empty it returns ( c_diRuneError , udiLength=0 ). Otherwise, if the encoding is invalid, it returns ( c_diRuneError , udiLength=1` ). Both are impossible results for correct, non-empty UTF-8. An encoding is invalid if it is incorrect UTF-8, encodes a rune that is out of range, or is not the shortest possible UTF-8 encoding for the value. No other validation is performed. InOut: Scope Name Type Comment Return DecodeLastRune RUNE Input pbyData POINTER TO BYTE Pointer to the first byte in memory udiSize UDINT Size of the memory in bytes Output udiLength UDINT Length of the rune in bytes udiIndex UDINT Index of the last rune (depending to the bytes in memory)

DecodeRune (FUN) ¶ FUNCTION DecodeRune : RUNE Unpacks the first UTF-8 encoding in pbyData and returns the rune and its length in bytes. If pbyData is empty it returns ( c_diRuneError , udiLength=0 ). Otherwise, if the encoding is invalid, it returns ( c_diRuneError , udiLength=1` ). Both are impossible results for correct, non-empty UTF-8. An encoding is invalid if it is incorrect UTF-8, encodes a rune that is out of range, or is not the shortest possible UTF-8 encoding for the value. No other validation is performed. InOut: Scope Name Type Comment Return DecodeRune RUNE Input pbyData POINTER TO BYTE Pointer to the first byte in memory udiSize UDINT Memory size in byte Output udiLength UDINT Lenght of the rune in bytes

DecodeRune2 (FUN) ¶ FUNCTION DecodeRune2 : RUNE Decodes a rune out of two segments and returns its length and offset. If rune is complete in the first segment, than no offset is returned. An encoding is invalid if it is incorrect UTF-8, encodes a rune that is out of range, or is not the shortest possible UTF-8 encoding for the value. No other validation is performed. InOut: Scope Name Type Comment Return DecodeRune2 RUNE Input pbyData POINTER TO BYTE Pointer to the first byte of the first segment udiSize UDINT Size of the first segment in bytes pbyData2 POINTER TO BYTE Pointer to the first byte of the second segment udiSize2 UDINT Size of the second segment in bytes Output udiLength UDINT Lenght of the rune in bytes udiOffset UDINT Offset of the second segment needed bytes
