I just realized I made a big mistake in one of my Pages documents : for a Romanized version of a Hebrew text, to represent the letters ayn and aleph I used left and right single quotes instead of (for example) left and right glottal stops, as defined in ISO 259-3.
Now Pages understandably interprets single quotes as single quotes, and makes them left or right as it sees fit to have a logical presentation. As a result my text is now a mess.
The most natural idea would be to do two successive replaces, replace all left single quotes by left glottal stops and right single quotes by right glottal stops. Unfortunately, Pages' search engine does not distinguish between left or right single quotes. Any ideas ?
