UnicodeToUpper¶

Transform unicode string to uppercase.

Declaration¶

Source position: unicodedata.pas line 495

function UnicodeToUpper(const AString: UnicodeString; 
                       const AIgnoreInvalidSequence: Boolean; 
                       out AResultString: UnicodeString) : Integer;

Arguments¶

Name	Description
AString	String to convert to uppercase.
AIgnoreInvalidSequence	Set to true to ignore invalid characters.
AResultString	Uppercase equivalent of AString.

Function result¶

Zero if all went well, nonzero indicates an error.

Description¶

UnicodeToUpper transforms a UTF16 unicode string AString to its uppercase equivalent and returns this in AResultString. If the transformation was successful, then the function returns 0. A nonzero return value means an error occurred. AResultString will remain untouched in that case.

If a character in AString cannot be found in the unicode data tables, an error will be reported, unless AIgnoreInvalidSequence is set to True, in which case the character will be copied as-is to the output.

Unicode collation data can be loaded using RegisterCollation or LoadCollation

Errors¶

On error, a nonzero value will be returned.

Name	Description
UnicodeToLower	Transform unicode string to lowercase.
RegisterCollation	Register a new collation.
LoadCollation	Load a binary collation data file from file.
