Subscript Problem

An apparent bug with Wikidot.com syntax makes a subscript of just "0" invisible. This code:

||  || **x** || **//x//** ||
|| **(zero)** || x,,0,, || //x//,,0,, ||
|| **1** || x,,1,, || //x//,,1,, ||
|| **2** || x,,2,, || //x//,,2,, ||
|| **3** || x,,3,, || //x//,,3,, ||
|| **k** || x,,//k//,, || //x//,,//k//,, ||
|| **00** || x,,00,, || //x//,,00,, ||

produces:

x x
(zero) x0 x0
1 x1 x1
2 x2 x2
3 x3 x3
k xk xk
00 x00 x00

The workaround I discovered was to specify the "0" as "raw" unparsed text. So:

**Invisible "0":** //x//,,0,, (regular syntax)
**Visible "0":** //x//,,@@0@@,, (making "0" unparsed)

produces:

Invisible "0": x0 (regular syntax)
Visible "0": x0 (making "0" unparsed)

Bold Invisibility

You may have noticed I wrote "(zero)" not "0" in the first column of the table.

While making the table I found that >>**0**<< produces »0« (you're presumably not seeing a bold zero).

Again, the workaround seems to be to mark 0 as unparsed:

**@@0@@**

producing 0.

(The same problem showed up trying to display just "0" in teletype text.)
