Escape Sequences
Mercurial’s templating engine recognizes the most commonly used escape sequences in strings. When it sees a backslash (\) character, it looks at the following character and substitutes the two characters with a single replacement, as described below:
\: Backslash, \, ASCII 134.\n: Newline, ASCII 12.\r: Carriage return, ASCII 15.\t: Tab, ASCII 11.\v: Vertical tab, ASCII 13.\{: Open curly brace, {, ASCII 173.\}: Close curly brace, }, ASCII 175.
As indicated above, if you want the expansion of a template to contain a literal \, {, or { character, you must escape it.
