## Description
Transer 多言語ページ翻訳 connects your WordPress site to the [transer.io](https://www.transer.io/)
server-side translation API. It is designed specifically for sites whose original
content is written in Japanese.
#### Why a Japanese-first engine matters
General-purpose translation tools treat Japanese as one language among many. Japanese
source text has structural habits that break those tools, and the engine behind
this plugin is built around them:
* **Japanese-era dates**: Reiwa, Heisei and Showa dates are resolved to the correct
Gregorian year rather than being transliterated or dropped.
* **Kana-heavy sentences**: Text written largely in hiragana is ambiguous to morphological
analysis. The engine disambiguates word boundaries instead of guessing at them.
* **Decorative markup**: Japanese sites often split words across `` tags
for styling. The engine reads through that markup so a single word is not translated
as several fragments.
The full HTML of the page is sent as-is, so context is preserved across the whole
document rather than being lost sentence by sentence. The translated page is then
rendered server-side, and multilingual SEO tags such as `hreflang` and `canonical`
are generated automatically.
#### Key features
* **Server-side translation**: The page is translated before it reaches the browser,
so search engines and visitors receive the same finished HTML.
* **Automatic multilingual SEO tags**: `canonical` and `hreflang` tags are inserted
automatically for every contracted language.
* **Automatic language-switcher UI**: No shortcode placement required. The language
switcher is automatically shown on both the original and translated pages.
* **Multilingual sitemap**: Visiting `/transer-sitemap.xml` dynamically generates
a sitemap with per-language `hreflang` annotations.
* **No server configuration required**: No `.htaccess` rewriting or web-server
rewrite rules are needed. The plugin detects language-prefixed URLs (e.g. `/en/
about`) during WordPress’s `init` hook.
#### A transer.io account and API key are required
Using this plugin requires a free account and API key from [transer.io](https://www.transer.io/).
The first language is free of charge.
### External services
This plugin connects to transer.io, a third-party server-side translation API operated
by Hippotech USA Inc. (the same company that develops this plugin), in order to
translate your page content into the languages you configure.
* **What is sent, and when**: When a visitor requests a page in a language other
than your site’s original language, the plugin captures the full HTML output
of that page (via an output buffer) and sends it, together with the requesting
hostname, URL path, source language code, and your configured list of contracted
languages, to the transer.io translation endpoint (`{configured base_url, default
https://api.transer.io}/translate-page`). No request is sent when a page is viewed
in the original language.
* **Authentication**: Requests are authenticated using an API key that you obtain
yourself from your transer.io account and enter on the plugin’s settings screen.
No API key is hard-coded in the plugin.
* **On request failure**: If the request to transer.io fails for any reason, the
plugin falls back to displaying the original, untranslated page; it never blocks
page rendering.
* **Data disclosure**: The HTML sent to transer.io reflects the page as rendered
by WordPress; it does not include values a visitor may have entered into forms
on the page.

## Installation
1. Upload the plugin files to `/wp-content/plugins/transer-translate`, or install

2. Activate the plugin from the “Plugins” screen.
3. Go to “Settings” > “Transer 多言語ページ翻訳” and enter the API key and list of
contracted languages obtained from [transer.io](https://www.transer.io/), then
save.
## FAQ
### Where does the actual translation happen?
All translation processing happens on transer.io’s servers (the translate.service
API). This plugin sends the HTML generated by WordPress to that service and outputs
the translated HTML it receives; it does not perform translation itself.
### Do I need to configure server-side rewrite rules?
No. The plugin detects the language prefix in the URL early during WordPress’s `
init` hook, so no `.htaccess` or web-server rewrite configuration is required.
### Is it free to use?
The first language is free (with a monthly traffic limit). See [transer.io](https://www.transer.io/)
for details.
### Which languages are supported?
More than 120 languages are supported, including English, Simplified Chinese, Traditional
Chinese, Korean, Spanish, French and Portuguese. For 16 of these, the translation
engine has been tuned further and is offered as a recommended language set.
### What kinds of websites is this suited for?
It is built for sites whose original content is written in Japanese and that need
to reach readers in other languages. Typical examples include municipal and tourism
websites serving inbound visitors, cross-border e-commerce stores selling overseas,
and corporate websites that publish news and IR material for a global audience.
### Does it handle specialist terminology?
The translation engine is tuned for a range of professional fields, including medicine,
law, chemistry, education, finance and accounting, real estate, manufacturing and
machinery, IT and software development. Technical terms and proper nouns can also
be managed centrally on transer.io, so that they are rendered consistently across
every page of your site.
