These are some regular expressions I use for formatting purposes:

Pattern	Replace by	Purpose
`^(?:\+\|-\|\x{2212})?(?:(?:\d{1,3}?(?:\,\d{3})\|\d+)\.?\d\|\d*\.?\d+)(?:[Ee][+-]?\d+)?$`	N/A	Match a number
`(?<!(<[Nn][Oo][Ww][Ii][Kk][Ii]>[^\n])\|\{\|\})(?<=\n)\\|\s(?!-\|<\/[Nn][Oo][Ww][Ii][Kk][Ii]>\|\{\|\})`	`\|`	Space out pipe characters in tables (one cell per line)*

* Requires support for variable-length lookaheads and lookbehinds
