The lib used to return "" for both properly detected ASCII and
detection failure. And the tool would return "ascii/unknown".
Make a proper distinction between the 2 cases.
Mostly generated with a script from Wikipedia data (only the typical
positive ratio is slightly modified).
This is a first test before adding my generating script to the main tree.
Control characters, carriage, symbols and numbers.
Also add a constant for illegal characters (not used for now).
This will allow easier processing and charmap reading.
Some charsets are simply not supported (ex: fr:iso-8859-1), some are
temporarily deactivated (ex: hu:iso-8859-2) and some are wrongly
detected as closely related charsets.
These were broken (or not efficient) from the start, and there is no
need to pollute the `make test` output with these, which may make us
miss when actual regressions will occur. So let's hide these away for
now until we can improve the situation.
... and some minor space issues.
Some explicit parentheses were needed to make precedence obvious.
Warning was:
"warning: suggest parentheses around ‘&&’ within ‘||’ [-Wparentheses]"
I realize that the language information a text has been written in is
very important since it would completely change the character
distribution. Our test files should take this into account, and we
should create several test files in different languages for encoding
used in various languages.
Taken from French page about ISO-8859-1:
https://fr.wikipedia.org/wiki/ISO_8859-1
... and Hungarian Wikipedia page about ISO-8859-2:
https://hu.wikipedia.org/wiki/ISO/IEC_8859-2
We don't have support for ISO-8859-1, and both these files are detected
as "WINDOWS-1252" (which is acceptable for iso-8859-1.txt since
Windows-1252 is a superset of ISO-8859-1). ISO-8859-2 support is
disabled because the ISO-8859-1 file would be detected as ISO-8859-2,
which would in turn be a clear error.
It is still ON by default, which means both shared and static libs will
be built and installed (current behavior), but it makes it possible to
disable the build of a static lib.

Contains text taken from Wikipedia on EUC-KR page in Korean.

I added it as a simili-subtitle file because as the original Mozilla
paper says: "The input text may contain extraneous noises which have no
relation to its encoding, e.g. HTML tags, non-native words".
Therefore I feel it is important to have test files a little noisy if
possible, in order to test our resistance to noise in our algorithm.
It was not clear if our naming followed any kind of rules. In particular,
iconv is a widely used encoding conversion API. We will follow its
naming.
At least 1 returned name was found invalid: x-euc-tw instead of EUC-TW.
Other names have been uppercased to follow naming from `iconv --list`
though iconv is mostly case-insensitive so it should not have been a
problem. "Just in case".
Prober names can still have free naming (only used for output display
apparently).
Finally HZ-GB-2312 is absent from my iconv list, but I can still see
this encoding in libiconv master code with this name. So I will
consider it valid.
... to stay backward compatible with previous behavior.
About detection failure, our in-code documentation says:
"@return name of charset on success and "" on failure or pure ascii."
This behavior had been broken by commit 3a518c0, which returned NULL
instead. Our command-line tool was the first victim, segfaulting on
ASCII files.
