Yes, see screenshot attached. Typing any Latin character between the
Tibetan text and the U+200B makes the visible glyph vanish.

The Monlam Uni Ochan1 font I'm using can be obtained from the Monlam
Bod-yig v2 zip file on my Tibetan fonts site,
http://www.aerifal.cx/~dalias/bodyig/fonts/

(The alternative is the upstream site that distributes it only as a
Windows .exe file, www.lobsangmonlam.org.)

My site has it listed under legacy fonts, but this is just because it
has glyphs on top of other script ranges that do not belong to
Tibetan, as well as other non-Unicode fonts packaged with it; the font
in question here does have valid OpenType tables and works fine for
displaying Unicode-encoded Tibetan on both Linux/Pango and Windows.
