String Objects
Strings in DolphinDB use UTF-8 character encoding. We also have the following functions that support the use of regular expressions: regexFind, regexReplace, regexCount.
Note that regular expression standards used by DolphinDB vary depending on the operating system, as follows:
-
For Linux, Extended Regular Expressions (ERE) based on the POSIX standard is employed.
-
For Windows, ERE based on the C++ standard library is used.
