  class function ToUpper(const AString: UnicodeString) : UnicodeString

Description

ToUpper converts the Unicode character AChar or string AString to uppercase. Options determines the behaviour of the conversion: if AOptions contains coIgnoreInvalidSequence then no exception will be raised when the string or character contains an invalid Unicode sequence. The default behaviour is to raise an EArgumentException exception when this happens.

Errors

If an invalid character is encountered, an EArgumentException exception is raised, unless coIgnoreInvalidSequence is specified in the options.
