UEB: Sometimes, two consecutive vertical bars emit Unicode symbol for double vertical bar

[rob-aph]

Consider the following:

<math>
	<mo>|</mo>
	<mo>|</mo>
	<mn>-3</mn>
	<mo>|</mo>
	<mo>+</mo>
	<mo>|</mo>
	<mn>2</mn>
	<mo>|</mo>
	<mo>|</mo>
</math>

With this, I get the following output: ‖⠐⠤⠼⠉⠸⠳⠐⠖⠸⠳⠼⠃⠸⠳⠸⠳

The easy fix is to add braille for the Unicode char ‖ (U+2016). If it isn't ⠸⠳⠸⠳, let me know. I've checked that in.

The harder problem is that the clean up for two|s in a row is incorrect. The speech is messed up.

With this fix, one of the vertical bars is missing in the UEB output. I'm getting: ⠸⠳⠐⠤⠼⠉⠸⠳⠐⠖⠸⠳⠼⠃⠸⠳⠸⠳

Should be: ⠸⠳⠸⠳⠐⠤⠼⠉⠸⠳⠐⠖⠸⠳⠼⠃⠸⠳⠸⠳

Not sure if this is a clue to your speech string problems or not.

Just checking in on this one. Are we any closer to a resolution? Is there anything I can do?
