\end_layout

\begin_layout Standard
Up to version 2013/03/31 v1.8, Babel’s “thai.ldf” changes character categories
 and the definitions for up-/dowcasing of letters (catcode, uccode, lccode)
 
\series bold
globally
\series default
.
 As a result, some high bit characters come out wrong in the output.
