Sudden Crash with item details

[ASopH]

Hello,
I have the following problem:
'Item detais' with this sequence:

$if($stricmp($left(%path%,4),http),📻,💿 )[%album%[ '('$year(%date%)')']$ifgreater(%totaltracks%,1, `'['%tracknumber%/%totaltracks%']',)]

Often when I click in the Playlist to a untagged file foobar crashes . This does often/but not always happen, and rarely it creates a crash-log.
If I remove the sequence by a "//" I had no mistakes.

annexed rarely crash-logs. I hope they can help.

Best regards
Arne

Thanks for the report and repro steps – I've reproduced the problem.

It's happening because the Windows API function Items details uses (ScriptString_pcOutChars) to work out how many characters fit in the available space is counting the emojis as two code points each, while I was under impression they were one code point each (but two code units in UTF-16). Other functions in that area of the Windows API (Uniscribe) seem to be doing the same.

I'll need to investigate a bit further about how to fix this. But it's affecting those two emojis as their code points in hex are above FFFF. I'd suggest avoiding them for now.

Hello!
Thanks for the information. The troubleshooting has made me a little crazy. I have the symbols once replaced by words.

Thank you and stay healthy.

Just a note to say I'm still working on a fix. I've needed to rewrite the word wrapping logic (which is complex due to font and colour code support).

Hopefully I'll have something to test in a few days or so.

Nice to hear. I'll take a look then.

Hi,

I have a development version available to test:

Download link

In that archive, within VS 2019 v142 Release\vc16\Release\ you'll find an .fb2k-component file that you can install in the usual way (you can ignore the .pdb file).

The crash should be gone, but I'd check that other Item details functionality like $set_font(), $rgb() and word wrapping is still working well if you were using those before.

Thanks!

Hello and thanks!
I've tested... crash seems to be gone, but the horizontal alignment in item details is broken. LEFT is ok, but CENTER looks like <
left center> and right is out of frame!
$rgb() seems to be ok, $set_font I'd never used.
$tab() with no effect (a long time ago). I believe, it's a DUI-problem. I don't have a hydrogenaudio-account to post this.

thanks for your time :-)

Thanks for testing!

I've put a fix in for the alignment – here's a new version.

$tab() has a bit of a history. In some contexts it's used for right-alignment and pseudo-columns. In Default UI, this is just in the status bar now, I believe. I assume you were after normal tab indentation support – it's not a simple matter so it's generally not supported in Columns UI.

Thanks for the info about $tab()!
It seems that the error is gone - the crash and the alignment.
I can see no other error in this case. You can close this if you want.

Thanks again :-)

Great. Thanks for testing!
