With indebtedness to the above post, this function capitalizes the first letter of every word except those that are less than a certain character length, which are assumed to be acronyms. If that's no issue, then you set the second argument to 0.

CREATE function [dbo].[f_camel_exc_short_words] (@InputString varchar(4000),@AcronymMaxLen INT )
RETURNS VARCHAR(4000)
AS
BEGIN

DECLARE @Index          INT
DECLARE @Char           CHAR(1)
DECLARE @PrevChar       CHAR(1)
DECLARE @Word           VARCHAR(255)
DECLARE @WordChar       CHAR(1)
DECLARE @OutputString   VARCHAR(255)
DECLARE @WordIndex      INT

SET @Word = ''
SET @OutputString = '' 
SET @Index = 1

WHILE @Index <= LEN(@InputString)+1
BEGIN
    SET @Char     = SUBSTRING(@InputString, @Index, 1)
    SET @PrevChar = CASE WHEN @Index = 1 THEN   ' '   ELSE   SUBSTRING(@InputString, @Index - 1, 1)  END

    --IF @Char IN (' ', ';', ':', '!', '?', ',', '.', '_', '-', '/', '&', '''', '(')
    --    SET @OutputString = @OutputString + @Char

    IF @PrevChar IN (' ', ';', ':', '!', '?', ',', '.', '_', '-', '/', '&', '''', '(','0','1','2','3','4','5','6','7','8','9') or @Index = LEN(@InputString)+1
    BEGIN
         SET @WordIndex = 1
        IF LEN(@Word) > @AcronymMaxLen 
        BEGIN
            WHILE @WordIndex <= LEN(@Word)
            BEGIN
                SET @WordChar = SUBSTRING(@Word,@WordIndex,1)
                if @WordIndex = 1  begin
                    SET @Word = STUFF(@Word,@WordIndex,1,UPPER(@WordChar))    end
                else    begin
                    SET @Word = STUFF(@Word,@WordIndex,1,LOWER(@WordChar))    end
                SET @WordIndex = @WordIndex + 1
            END
        END
        ELSE BEGIN
            SET @Word = UPPER(@Word)
        END
        set @OutputString = @OutputString + @Word
        SET @Word = ''
    END
    SET @Word = @Word + @Char
    SET @Index = @Index + 1
END  

return @OutputString

end
GO

So PRINT dbo.f_camel_exc_short_words ('PIONEER EURO BOND FUND CLASS C (NON-DIST) (EUR) (OFFSHORE) ISIN LU0119429891',4) returns Pioneer EURO BOND FUND Class C (NON-Dist) (EUR) (Offshore) ISIN LU0119429891

Hope it helps.
