Variants

UnicodeNotAllowed

[−] Expand description

This error occurs when a Unicode feature is used when Unicode support is disabled. For example (?-u:\pL) would trigger this error.

InvalidUtf8

[−] Expand description

This error occurs when translating a pattern that could match a byte sequence that isn't UTF-8 and allow_invalid_utf8 was disabled.

UnicodePropertyNotFound

[−] Expand description

This occurs when an unrecognized Unicode property name could not be found.

UnicodePropertyValueNotFound

[−] Expand description

This occurs when an unrecognized Unicode property value could not be found.

EmptyClassNotAllowed

[−] Expand description

This occurs when the translator attempts to construct a character class that is empty.

Note that this restriction in the translator may be removed in the future.
