I have written a parser for TLV and I would like it not to give an error when it encounters an unknown tag, but also to parse it as a tag named "unknown tag". Unfortunately, the length of the tags is not fixed, they can be 2 or 4 and The search space is high, do you have an idea to solve the problem?

I am writing some code to parse GS1 barcodes. There are a few App Idents (AIs) in the specification that I don't understand. For example, AI 426 (https://www.gs1.org/standards/barcodes/application-identifiers/426?lang=en):
This is saying that the data must be 3 digits (the app ident) followed by another 3 digits for the country code (e.g. 426824). As such it is a fixed length field. The bit I don't understand is that it also says it requires a FNC1 delimiter. Surely if it is a fixed length field it won't require a delimiter after the data? Can anyone shed any light as to why the specification says this, or is it likely to be a mistake?
I have a query parameter defined in RAML as of type Integer and have used APIKit to generate flows and validation implementation. When I enter the invalid value 1]3 for this field, I get the following validation error, as expected:
"Invalid value '1]3' for query parameter offset. Invalid type String, expected Integer"
However, if I enter the single character ] I do not get a validation error, but it looks like this causes a fault in YAML parsing as the character is interpreted as YAML and not text to be validated.
"Invalid value ']' for query parameter offset. Underlying error while parsing YAML syntax: 'while parsing a block node
in 'reader', line 1, column 1:
]
^
expected the node content, but found ']'
To me both inputs should return the first error shown. This behaviour is also triggered by input of other YAML special characters such as : , ' and ,, where they are the only character entered in the query parameter.
So my question is, how can I get these error cases to return consistent format error messages - that is, of the first example, without mapping both to a custom Mule error? Passing the error text on to consumers as-is makes for an inconsistent user experience. Or perhaps this is not the intention, and these errors should always be mapped to a custom error?
Mule runtime version 4.3.0
APIKit version 1.4.1
When I try to change Group attributes using C++ Native code, I get this error: 8007203c. What does this error code refer to? I can't find details regarding this in documents.
The error code is defined as ERROR_DS_ENCODING_ERROR in winerror.h:
//
// MessageId: ERROR_DS_ENCODING_ERROR
//
// MessageText:
//
// An encoding error has occurred.
//
#define ERROR_DS_ENCODING_ERROR 8252L
An easier way to lookup error code is to search in The Magic Number Database: https://www.magnumdb.com/search?q=8007203c
So this is probably an encoding (ansi vs unicode) issue or maybe using special characters that should be escaped. From Active Directory: Characters to Escape:
As for my knowledge, this error occurs if there is an invalid code page, invalid characters or an encoding error (can't find the reference/documentation about it yet).
Maybe there are special characters in your group names which cause this behavior.
I scraped some text from the internet, which I put in an UTF8String. I can use this string normally, but when I select some specific characters (strange character with accents, like in my case ú), which are not part of the UTF8 standard, I get an error, saying that I used invalid indexes. This only happens when the string contains strange characters; my code works with normal string that do not contain strange characters.
Any way to solve this?
EDIT:
I have a variable word of type SubString{UTF8String}
When I use do method(word), no problems occur. When I do method(word[2:end]) (assuming length of at least 2), I get an error in case the second character is strange (not in UTF8).
Julia does indexing on byte positions instead of character position. It is way more efficient for a variable length encoding like UTF-8, but it makes some operations use some more boilerplate.
The problem is that some codepoints is encoded as multiple bytes and when you slice the string from 2:end you would have got half of the first character (witch is invalid and you get an error).
The solution is to get the second valid index instead of 2 in the slice. I think that is something like str[nextind(str, 1):end]
PS. Sorry for a less than clear answer on my phone.
EDIT:
I tried this, and it seems like SubString{UTF8String} and UTF8String has different behaviour on slicing. I've reported it as bug #7811 on GitHub.
Sorry, I am unable to validate this document because on line 1200 it contained one or more bytes that I cannot interpret as utf-8 (in other words, the bytes found are not valid values in the specified Character Encoding). Please check both the content of the file and the character encoding indication.
The error was: utf8 "\xD8" does not map to Unicode
i would be thankful to know what exactly should i do, my website is : http://dailysahara.com/
The issue, as stated by the validator, is that you have some invalid UTF-8 in your document. It appears to be in the box on the left of the site with the four tabs "Tags", "Comments", "Recents", and "Popular". It shows up to me as a black square like this: �. If you remove that, you should be able to validate your site.
