# LaTeX::ToUnicode::Tables(3pm)

Character tables for LaTeX::ToUnicode

## NAME

LaTeX::ToUnicode::Tables - Character tables for LaTeX::ToUnicode

## VERSION

version 0.54

## CONSTANTS

### @LIGATURES

Standard TeX character sequences (not \\commands) which need to be replaced: `"---"` with U+2014 (em dash), etc.  Includes: em dash, en dash, inverted exclamation, inverted question, left double quote, right double quote, left single quote, right single quote. They are replaced in that order.

### %MARKUPS

Hash where keys are the names of formatting commands like `"\tt"`, without the backslash, namely: `"bf cal em it rm sc sf sl small tt"`. Values are the obvious HTML equivalent where one exists, given as the tag name without the angle brackets: `"b em i tt"`. Otherwise the value is the empty string.

### %ARGUMENT\_COMMANDS

Hash where keys are the names of TeX commands taking arguments that we handle, without the backslash, such as `"enquote"`. Each value is a reference to a list of two strings, the first being the text to insert before the argument, the second being the text to insert after. For example, for `"enquote"` the value is ``"["`", "'"]"``. The inserted text is subject to further replacements.

Only three such commands are currently handled: `"\emph"`, `"\enquote"`, and `"\path"`.

### %CONTROL\_SYMBOLS

A hash where the keys are non-alphabetic `"\command"`s (without the backslash), other than accents and special cases. These don't take arguments. Although some of these have Unicode equivalents, such as the `"\,"` thin space, it seems better to keep the output as simple as possible; small spacing tweaks in TeX aren't usually desirable in plain text or HTML.

The values are single-quoted strings `'\x{...}'`, not double-quoted literal characters \<"\\x{...}"\>, to ease future parsing of the TeX/text/HTML.

This hash is necessary because TeX's parsing rules for control symbols are different from control words: no space or other token is needed to terminate control symbols.

### %CONTROL\_WORDS

Keys are names of argument-less commands, such as `"\LaTeX"` (without the backslash). Values are the replacements, often the empty string.

### %SYMBOLS

Keys are the commands for extended characters, such as `"\AA"` (without the backslash.)

### %ACCENT\_SYMBOLS

Two-level hash of accented characters like `"\'{a}"`. The keys of this hash are the accent symbols (without the backslash), such as ``"`"`` and `"'"`. The corresponding values are hash references where the keys are the base letters and the values are single-quoted `'\x{....}'` strings.

### %ACCENT\_LETTERS

Same as `%ACCENT_SYMBOLS`, except the keys are accents that are alphabetic, such as `"\c"` (without the backslash as always).

As with control sequences, it's necessary to distinguish symbols and alphabetic commands because of the different parsing rules.

### %GERMAN

Character sequences (not necessarily commands) as defined by the package \`german'/\`ngerman', e.g. `""a"` (a with umlaut), `""s"` (german sharp s) or ``"`"`` (german left quote). Note the missing backslash.

The keys of this hash are the literal character sequences.
