Filter and escalation workflow considerations
Some server-side workflow actions call byte-oriented filter functions, such as LENGTH, SUBSTR, and STRSTR. Character -oriented equivalents, such as LENGTHC, SUBSTRC, and STRSTRC, also exists. Because UTF-8, Chinese, Japanese, and Korean characters can occupy one or more bytes, the byte-oriented and character-oriented lengths and offsets are different. When creating workflow actions, be aware of the difference. For example:
- LEFT($8$, 3) extracts a prefix of no more than 3 bytes from field 8.
- LEFTC($8$, 3) extracts a prefix of no more than 3 characters from field 8.
