Comment # 4 on bug 1173907 from Steffen Winterfeldt

Thanks!

I've reproduced the issue, and found the cause:

The allowed chars are (correctly) Yast::String.CPrint:

https://github.com/yast/yast-network/blob/master/src/lib/y2network/widgets/wireless_essid.rb#L95-L97

which amounts to 'printable + whitespace:

https://github.com/yast/yast-yast2/blob/master/library/types/src/modules/String.rb#L577-L580

which are defined here:

https://github.com/yast/yast-yast2/blob/master/library/types/src/modules/String.rb#L42-L43

But - oops - SPACE_CHARS doesn't include the space char!
