multiByteReg top-level property
A regular expression that matches any non-ASCII (multi byte) character.
This is useful for detecting characters outside the standard ASCII range, such as characters from non-Latin scripts (e.g., Khmer, Chinese, Arabic), emoji, and other symbols.
Matches any character not in the ASCII range (0x00 to 0x7F).
Implementation
RegExp multiByteReg = RegExp(multiByteRegStr);
