There is no valid letters in 128-159 range for ISO LATIN 1 (2,3,4...)
it is so called C1 control area, this may be a cursor moving codes in xterm
for example.
If you look the bookmark from different terminals with different display
charsets you will look all chars correctly.
Unfortunately, if you add new links to bookmark from different terminals,
8bit chars will be saved properly from one terminal only,
if matching assume_local_charset or META inside bookmarks.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
All Internet services recognize "us-ascii" for 7bit characters, <128 only.
To see any character >127 with lynx you *should* choose
display character set in Lynx Options Menu according to your
local font installed. To check your font go http://lynx.browser.org
and look for Lynx 2.8 source breakout,
browse *.html files in test/ subdirectory there.
For comparison try "7 bit approximation" in _Lynx_.
Details of charsets mapping can be found in src/chrtrans/ subdirectory.
