How to apply the star (*) to only a few of the literates in listings environment?

Question

I have a problem with the definition of literate:

\lstset{
  numbers=left, numberstyle=\footnotesize, stepnumber=1, numbersep=12pt,
  frame=none, framesep=7pt,
  breaklines=true,
  basicstyle=\footnotesize,
  showstringspaces=false,
  upquote=true,
  columns=fullflexible,
  showstringspaces=false,
  commentstyle=\color{gray}\upshape,
  stringstyle=\color{black}\ttfamily,
  keywordstyle=\color{darkblue},
  captionpos=b,
  extendedchars=true,
  literate=
  *{0}{{{\color{DarkGreen}0}}}1
  {1}{{{\color{DarkGreen}1}}}1
  {2}{{{\color{DarkGreen}2}}}1
  {3}{{{\color{DarkGreen}3}}}1
  {4}{{{\color{DarkGreen}4}}}1
  {5}{{{\color{DarkGreen}5}}}1
  {6}{{{\color{DarkGreen}6}}}1
  {7}{{{\color{DarkGreen}7}}}1
  {8}{{{\color{DarkGreen}8}}}1
  {9}{{{\color{DarkGreen}9}}}1
  {á}{{\'a}}1
  {é}{{\'e}}1
  {í}{{\'i}}1
  {ó}{{\'o}}1
  {ú}{{\'u}}1
}

The coloring of the numerals has the be ignored inside comments and strings (hence the * at the beginning) BUT the rules for the acute accents shouldn't. This is because source code with strings in different languages is included later with the \lstinputlisting option, and if the unicode characters are not changed, it crashes.

So, does anyone know any way to apply the * to only part of the literate definitions? I tried to define them in the specific listing where the file is included, but a second literate eliminates the previous definitions.

PS: I tried to change the encoding of the file with the \inputencoding=utf8/latin1 as well, but it makes the compilation REALLY slow and returns a Missing $ inserted. error.

EDIT: I'm adding a fully compilable MWE that I think represents the problem. The output highlights the colors according to the rules defined for Javascript. However, as I said before, in line 22 (see output) the numerals are in green, even being a comment. If the * is added before the numerals, the compilation crashes because the unicode characters inside the strings are not replaced.

(NOTE: the javascript doesn't make any sense)

While code snippets are useful in explanations, it is always best to compose a fully compilable MWE that illustrates the problem including the \documentclass and the appropriate packages so that those trying to help don't have to recreate it. While solving problems is fun, setting them up is not. Then those trying to help can simply cut and paste your MWE and get started on solving problem. — Peter Grill, Nov 20 '12 at 20:02
Thanks, I've just added an example. Sorry for not doing it at the beginning :\ — aleyenda, Nov 20 '12 at 21:38

@Speravir I know... but leaving a reminder in the comments can't hurt. — jub0bs, Mar 06 '14 at 22:03

Remark:

The literate feature does not work too well for numbers inside strings and comments. The spaces after the numbers are gobbled. As workaround option keepspaces can be used, see question "listings bug: space after literate replacement lost with spaceflexible/fullflexible columns" (Thanks Jubobs for the hint).

Limitation:

Numbers inside identifiers are colored, too.

Package `listingsutf8`

The trick with converting UTF-8 to a 8-bit encoding via package listingsutf8 only works for \lstinputlisting. Thus the code needs to be put into a separate file. But then utf8/latin1 (or utf8/x-iso-8859-1) works together with literate=*... for the digits excluding comments.

One problem with you approach is that literal replacements of digits also occur in strings, which the OP doesn't want. You can get around that problem by using the following definition for your \lstnumcolor macro instead: \newcommand*{\lstnumcolor}{\ifnum\lst@mode=\lst@Pmode \color{DarkGreen}\fi}. See this answer in which I used the same trick. — jub0bs, Mar 06 '14 at 09:46
@Jubobs: Thanks, answer updated. However severe limitations remain, see answer. — Heiko Oberdiek, Mar 06 '14 at 09:54
The space problem can be fixed by using the keepspaces option. See http://tex.stackexchange.com/a/46695/21891. — jub0bs, Mar 06 '14 at 11:36
