Description Kurt Hindenburg 2006-08-06 06:28:38 UTC 
Version:            (using KDE KDE 3.5.4)
Installed from:    Compiled From Sources
OS:                Linux

Email: Jonas Hurrelmann <j@outpo.st>

the latest konsole has a bug decoding UTF-8 (introduced with the "speedup"  patch).
When checking for the next control code in TEmulation::onRcvBlock the loop runs until len but as the toUnicode call uses one additionally char it faces a 0 at the end causing a wrong character at the end of each block.

Not needed for KDE4 since this code is no longer used.
