Description Milan Kerslager 2010-03-24 12:06:59 UTC 
I'm doing network installation. When I use "lang=cs" as kernel parameter, the text screen indicating download of install.img is garbled. When I delete this parameter, there is a text screen to pick up language, but in this case the font initialization is done properly.

Proposing as F13Blocker.
Comment 2 Ales Kozumplik 2010-03-31 13:38:06 UTC 
Here's what's going on: 
Newt (the TUI used by Anaconda) and especially s-lang (a library for interactive applications used by newt) handle UTF output according to the setting of the LANG environment variable at the moment of newtInit(). This is still en_EN.UTF-8 if language is set from a dialog, but already cs_CZ.UTF-8 when set from the kernel command line. But to keep the initrd.img small, we only include locale information for english so s-lang doesn't know how to compute character lengths etc if LANG is set to Czech.

Patch coming soon.

Comment 6 Adam Williamson 2010-05-03 16:12:56 UTC 
gack. we missed this because we were skipping MODIFIED blocker bugs during the blocker reviews :(

if this is only a cosmetic bug that only affects one screen during text install while using a rather obscure kernel parameter...I don't think it's a blocker. if we'd reviewed this earlier in the process I'd have wanted to take the fix anyway, but now it seems a bit late. jlaska, oxf13, your opinions?

this change went in March 31st, and has been in composes since then, so a little late to put the bullet back in the gun.  This just needs to be confirmed as fixed.
Comment 8 Adam Williamson 2010-05-04 00:30:24 UTC 
oh, sorry, missed that the fix had gone in. in that case, there's no problem. i should be able to test it in a minute.

Comment 9 Adam Williamson 2010-05-04 00:40:06 UTC 
Testing with TC1, whether selecting Czech from the list or specifying lang=cs, the text screen that follows keyboard selection seems to look the same; there's a couple of garbage characters at the right hand end of the very top line, but the rest looks fine. I've seen those same garbage characters in rescue mode too, so I think that's a more general bug. Aside from that, everything seems to behave okay, so I think this is fixed. It seems to proceed to the graphical portion of the installation fine either way.
