Improving Arabic (RTL) Support and Enabling Edge TTS Languages**

[darkwhispar-web]

Dear Developer,

Your software is exceptional, clean, and highly professional. To make it even better for Arabic-speaking users, I would like to propose two technical enhancements regarding RTL (Right-to-Left) formatting and Edge TTS support.

1. ePub RTL Formatting Improvements**

Currently, Arabic text renders correctly but lacks proper RTL layout and alignment for mixed-language sentences. Please incorporate the following CSS into style.css to stabilize mixed text and protect technical terms from being reversed:

html, body, .calibre, .body {
    direction: rtl !important;
    unicode-bidi: isolate !important;
    text-align: right !important;
}

p, span, div, li {
    unicode-bidi: isolate !important;
}

.programlisting, 
.fm-code-in-text, 
.fm-code-in-text1, 
.fm-code-in-text2, 
code, pre, tt, 
.fm-code-continuation-arrow, 
.fm-code-continuation-arrow1 {
    direction: ltr !important;
    unicode-bidi: embed !important;
    display: inline-block;
    text-align: left !important;
}

.body {
    color: black;
    display: block;
    font-family: "Verdana", "sans-serif";
    font-size: 1em;
    line-height: 1.4;
    margin: 1em 0;
}

.body1 {
    color: black;
    display: block;
    font-family: "Verdana", "sans-serif";
    font-size: 1em;
    line-height: 1.4;
    text-align: center;
    margin: 1em 0;
}

.calibre {
    display: block;
    font-size: 1em;
    line-height: 1.4;
    padding-left: 0;
    padding-right: 0;
    margin: 0 5pt;
}

.contenttable, .fm-contenttable3 {
    border-collapse: collapse;
    border-spacing: 2px;
    display: table;
    line-height: 1.4;
    margin-bottom: 5px;
    margin-top: 0;
    width: 100%;
    direction: rtl;
}

.fm-contenttable, .fm-contenttable1, .fm-contenttable2 {
    display: table-cell;
    vertical-align: top;
    padding: 2px 5px;
    border: black solid 2px;
    text-align: right; 
}

.co-summary-head, .fm-head, .fm-head1, .fm-head2, .tochead {
    color: #005;
    display: block;
    font-family: "Franklin Gothic Medium", "sans-serif";
    font-weight: bold;
    line-height: 1.4;
    text-align: right;
}

.copyright, .copyrighta, .copyrightb, .copyrightbody, .copyrightbody1 {
    text-align: center;
    direction: ltr; 
}

.programlisting {
    background-color: #f9f9f9;
    font-family: monospace;
    font-size: 0.83333em;
    white-space: pre-wrap;
    margin: 1em 0;
    padding: 10px 5px;
    border-radius: 4px;
}
.url, .url1 {
    color: #4080BF;
    text-decoration: none;
    direction: ltr;
    display: inline-block;
}

Also, please ensure the content.opf file includes the page progression attribute:

<spine toc="ncx" page-progression-direction="rtl">
</spine>

2. Full Edge TTS Language Support

While the software uses Edge TTS Cloud, the "Target Language" list does not currently include Arabic. Edge TTS natively supports over 55 languages. Unlocking these languages in the selection menu would make the TTS feature perfect for a global audience.

These improvements will significantly enhance the experience for Arabic users and align with the collaborative spirit of the Open Source community.

Thank you for your incredible work.

Best regards,
