RegExp.NoUTF8Check (gb.pcre)
Const NoUTF8Check As Integer = 1073741824 ' &H40000000
When the
UTF8 option is set, the validity of the pattern as a UTF-8 string is automatically checked.
If an invalid UTF-8 sequence of bytes is found, the
Compile method returns an error.
If you already know that your pattern is valid, and you want to skip this check for performance reasons, you can set the RegExp.NoUTF8Check
option. When it is set, the effect of passing an invalid UTF-8 string as a pattern is undefined. It may cause your program to crash.
Note that this option can also be passed to
Exec, to suppress the UTF-8 validity checking of subject
strings.
