Způsobují to velká písmena - ne všechna, asi polovina z nich, beze srandy:http://windowsphone.uservoice.com/forums/101801-feature-sug... ... "In WP 8 both HTC and Nokia users encouter problems with some capital letters while texting. Their presence leads to max. 70 characters per message. And no - it is not about national characters or reduced/full encoding.
E, T, Z, I, O, P, A, H, K, Y, X, B, N, M - if even one of these letters is typed, the available character count drops from 160 to 70.
This happens in different languages (incl. English), different devices (HTC, Nokia) and different OS versions (HTC before and after the update, Nokia still didn't receive Portico).
Avoiding those capital letters always leaves 160 characters to use."Jen na WP 8. Mám tři telefony s WP 7.5 a žádný to nedělá. WP 7.0 ten problém taky neměl.
