UnicodeToLower

Transform unicode string to lowercase

Declaration

Source position: unicodedata.pas line 370

function UnicodeToLower(

  const AString: UnicodeString;

  const AIgnoreInvalidSequence: Boolean;

  out AResultString: UnicodeString

):Integer;

Arguments

AString

  

String to convert to lowercase.

AIgnoreInvalidSequence

  

Set to true to ignore invalid characters.

AResultString

  

Lowercase equivalent of AString

Function result

Zero if all went well, nonzero indicates an error.

Description

UnicodeToLower transforms a UTF16 unicode string AString to its lowercase equivalent and returns this in AResultString. If the transformation was succesful, 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.
