zsh error after upgrade

fhsm · 04-09-2010, 09:23 PM

I recently upgraded from Ubuntu LTS (8.04) to 9.10 and zsh has stopped working. I'm using the same custom prompt and .zshrc I use on a number of other boxes without any problem but now I'm getting the following error:

Code:

prompt_fhsm_setup:32: bad math expression: illegal character: \

The referenced line is:

Code:

prompt_gfx_hyphen=$'\xe2\x94\x80'

Running echo $'\xe2\x94\x80' from zsh returns a hyphen as expected. I've tried to change that line without any impact on the error. Just doing some basic debugging by commenting lines out suggests that:

Code:

prompt_gfx_tbox="%{$fg_bold[$prompt_fhsm_color1]%}${prompt_gfx_tlc}%{$fg_no_bold[$prompt_fhsm_color1]%}${prompt_gfx_hyphen}"

is the line actually causing the error. When that line is removed the next line to call prompt_gfx_hyphen causes the error and so on. I've tried running zsh in a number of emulators without any impact on the error.

I suspect it has something to do with UTF-8.

Any help would be much appreciated.

Finally got this worked out, it's not a UTF-8 problem. It's a change to the way bold / normal text is specified. It was fg_bold[] it's now %B%F. Changing this fixes the problem.
