UnicodeToLower function

In unit unicodedata

Transform unicode string to lowercase.

Declaration

pascal

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 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.
