For the 16- and 32-bit representations, a computer receiving text from arbitrary sources needs to know which byte order the integers are encoded in. Unicode can be encoded in units of 8-bit, 16-bit, or 32-bit integers. Its presence interferes with the use of UTF-8 by software that does not expect non-ASCII bytes at the start of a file but that could otherwise handle the text stream. Which Unicode character encoding is used.īOM use is optional.The fact that the text stream's encoding is Unicode, to a high level of confidence.The byte order, or endianness, of the text stream in the cases of 16-bit and 32-bit encodings.The byte order mark ( BOM) is a particular usage of the special Unicode character, U+FEFF ZERO WIDTH NO-BREAK SPACE, whose appearance as a magic number at the start of a text stream can signal several things to a program reading the text: For the name of U+FEFF in Unicode and the alternative usage as a zero-width non-breaking space, see Word joiner. For the program used in X-ray absorption spectroscopy, see FEFF (software). For the airport in Central African Republic with the airport code FEFF, see Bangui M'Poko International Airport. )Īlso in relationships, using joins that are ≤ or ≥ will be much slower than fixed criteria, even if you have to gather a list of record IDs beforehand using another method."FEFF" redirects here. Performance issues are harder to identify in static code, but there are a few that BaseElements can pick up that are obvious issues when designing a solution.įor example a relationship with multiple predicates should have them in order of increasing complexity so that the fastest ones are resolve first, and that you should not have redundant criteria ( for example a relationship to a set of invoice items doesn't need the customer ID as well as the Invoice ID as the invoice ID will cover all of the items anyway. Not all warnings should be fixed, but you should be aware of what the warnings are and what is involved with them. Warnings are a useful way to see what might be an issue when a solution doesn't behave as expected. Having an Account that requires you to change the password on next login, but the Privilege Set doesn't allow password changes.You can also do it deliberately to achieve specific results. You can relate a number field to a text field in FileMaker, and it will work, but occasionally it will give you unexpected results. Using fields in a relationship join that are of a different field type. Warnings are any situation where there isn't anything structurally wrong with your solution ( these would be considered errors ), but where there are situations that may cause unexpected behaviour or just make life difficult. Do you still need this script to work, if so, could it use a different layout, or do you need to create a new one? What result were you trying to get out of this calculation, and can you fix it without that Function or does it need to be added back?īaseElements can't tell you specifically how to fix an error, it will depend on what you're trying to do and then how best to accomplish that.īaseElements Alerts can also include Warnings about issues in your solution. The options for fixing errors depend on the issue. Now your Step can't go to that Layout any more because it doesn't exist, or the Calculation is broken because it was using a Custom Function that doesn't exist. Errors occur in FileMaker solutions when you've built a Calculation or script that relies on other elements in the solution, but then you later delete those other elements.
