Subject: Handle STRING and COMPOUND_TEXT type text properties.
X-Git-Tag: release-3.5.0~63
X-Git-Url: http://git.openbox.org/?p=dana%2Fopenbox.git;a=commitdiff_plain;h=5d5714f01e1a7140847f6e7f2922d457f6bbe66a

Handle STRING and COMPOUND_TEXT type text properties.

STRING should be latin1 text (plus TAB and LF)
COMPOUND_TEXT should be encoded in the current locale.
