[-]test_iconv.lua fails due to missing hyphens[/-][+]test_iconv.lua fails on termux due to missing hyphens[/+]on Sep 15, 2026 Not sure this is an issue with this library. Seems that this lib doesn't define the names, they are handled by the underlying iconv lib.
If you mean to only update the test, to support both, then that should be possible I think. Simply try, and on failure rettry with the alternative first before failing the test.
Can you provide a stacktrace?
Looking at the tests; there's plenty of "utf-8" (which is the official name), and there's only 1 "utf8" and "utf16", so looks to me those two are explicitly there to test those aliases. Which termux apparently doesn't support.
I agree, this is not really an issue with the library itself.
Testing conversion from utf8 to utf-8 lua: test_iconv.lua:98: Failed to create a converter. object: Invalid input. stack traceback: [C]: in function 'assert' test_iconv.lua:98: in local 'check_one' test_iconv.lua:108: in main chunk [C]: in ?termux iconv fails in a similar way, e.g.
iconv -f utf8 -t utf-8 fp.utf8.txt iconv: conversion from utf8 unsupportedbut it will succeed when replacing
utf8byutf-8Updating the test is indeed a good idea. Since I'm far from being a lua expert, I'm currently studying how to do so.
BTW, do you know how these aliases are set on a linux system?Afaik they are hard coded in the iconv library.

on Sep 16, 2026 Muito obrigado.
I'm opening this as a separate issue, since although it's also on android/termux it's not directly related to the previously reported one regarding linking [see #20].
The provided test_iconv.lua works as exoected on my linux mint system, but on termux conversions to
utf8andutf16fail, and they also fail when usingiconvdirectly. This is because the termuxiconvonly understandsutf-8orutf-16. In other words, an hyphen is needed.
