UppercaseStripDiacritics

The UppercaseStripDiacritics procedure converts any lowercase characters in a text string into their uppercase equivalents and strips any diacritical marks from the text. The text string can be up to 32 KB in length.

PROCEDURE UppercaseStripDiacritics (textPtr: Ptr; len: Integer;
                                    script: ScriptCode);
textPtr
A pointer to the text string to be converted.
len
The number of bytes in the text string.
script
The script code of the script system whose resources are used to determine the results of converting characters.
DESCRIPTION
UppercaseStripDiacritics traverses the characters starting at the address specified by textPtr and continues for the number of characters specified in len. It converts lowercase characters in the text into their uppercase equivalents and also strips diacritical marks from the text string. This procedure combines the effects of the UppercaseText and StripDiacritics procedures.

The conversion uses tables in the string-manipulation ('itl2') resource of the script specified by the value of the script parameter. The possible values for script codes are listed in the chapter "Script Manager" of this book. You can specify smSystemScript to use the system script and smCurrentScript to use the script of the current font in the current graphics port.

If UppercaseStripDiacritics cannot access the specified resource, it generates an error code and does not modify the string. You need to call the ResError function to determine which, if any, error occurred. ResError is described in the Resource Manager chapter of the book Inside Macintosh: More Macintosh Toolbox.

SPECIAL CONSIDERATIONS
UppercaseStripDiacritics may move memory; your application should not call this procedure at interrupt time.
