This hack will let you add "spanish" characters to your
vbcode (á é í ó ú Ñ ñ ¡ ¿)! You can follow the same
format for other languages, (french, for example û ù, etc.)
This is a beta hack, mainly since it's my first "hack".
I created it on 2.2.1.

1)edit template vbcode_buttons

after:
"<input type="button" class="bginput" value="Quote" title="Insert Quote" onclick="vbcode(this.form,'QUOTE','')" onmouseover="stat('quote')">


insert:
<!-- extra character hack -->

<br>
<input type="button" class="bginput" value="á" onclick="extrachara('á')" title="á" onmouseover="stat('aaccent')">
<input type="button" class="bginput" value="é" onclick="extrachara('é')" title="é" onmouseover="stat('eaccent')">
<input type="button" class="bginput" value="í" onclick="extrachara('í')" title="í" onmouseover="stat('iaccent')">
<input type="button" class="bginput" value="ó" onclick="extrachara('ó')" title="ó" onmouseover="stat('oaccent')">
<input type="button" class="bginput" value="ú" onclick="extrachara('ú')" title="ú" onmouseover="stat('uaccent')">
<input type="button" class="bginput" value="Ñ" onclick="extrachara('Ñ')" title="Ñ" onmouseover="stat('capitalene')">
<input type="button" class="bginput" value="ñ" onclick="extrachara('ñ')" title="ñ" onmouseover="stat('lowerene')">
<input type="button" class="bginput" value="¡" onclick="extrachara('¡')" title="¡" onmouseover="stat('exinvert')">
<input type="button" class="bginput" value="¿" onclick="extrachara('¿')" title="¿" onmouseover="stat('quesinvert')">

<br>
<!-- /extra character hack -->

2. Edit vbcode.js:
At the end of the file, insert:

function extrachara(thechara) {
//inserts extra character text
document.vbform.message.value += thechara;
document.vbform.message.focus();
}
//end extra character text

3. Edit vbcode_language.js:
After:
closeall_text = "Close all open vbcode tags";

insert:

aaccent_text = "Insert 'á' into your message";
eaccent_text = "Insert 'é' into your message";
iaccent_text = "Insert 'í' into your message";
oaccent_text = "Insert 'ó' into your message";
uaccent_text = "Insert 'ú' into your message";
capitalene_text = "Insert 'Ñ' into your message";
loweene_text = "Insert 'ñ' into your message";
exinvert_text = "Insert '¡' into your message";
quesinvert_text = "Insert '¿' into your message";
