| <p>This set of charts shows the Unicode Collation Algorithm values for Unicode |
| characters. The characters are arranged in the following groups:</p> |
| <table cellspacing="0" cellpadding="4"> |
| <tr> |
| <th align="left"><i>Null</i></th> |
| <th class="x">Completely ignoreable (primary, secondary and tertiary levels)<br> |
| These include control codes and various formatting codes.</th> |
| </tr> |
| <tr> |
| <th align="left"><i>Ignorable</i></th> |
| <th class="x">Ignorable at a primary level, but not at a secondary or |
| tertiary level.<br> |
| These include most accents and diacritics.</th> |
| </tr> |
| <tr> |
| <th align="left"><i>Variable</i></th> |
| <th class="x">Characters that may be set to ignorable by a programmatic |
| switch.<br> |
| These include spaces, punctuation marks, and most symbols.</th> |
| </tr> |
| <tr> |
| <th align="left"><i>Common</i></th> |
| <th class="x">Characters that are none of the above, but not considered |
| letters.<br> |
| These include numbers, currency symbols, etc.</th> |
| <tr> |
| <th align="left"><i>Letters</i></th> |
| <th class="x">According to script</th> |
| </tr> |
| <tr> |
| <th align="left"><i>Unsupported</i></th> |
| <th class="x">Not explicitly supported in this version of UCA; uses |
| code-point order</th> |
| </tr> |
| </table> |
| <p>The characters* within each group are arranged in cells. The color of the |
| cell indicates the strength of the difference between that character and the <i>previous</i> |
| character in the chart, as follows.</p> |
| <table cellspacing="0" cellpadding="4"> |
| <tr> |
| <th colspan="2"><font size="3"><u>No Expansion</u></font> |

| <p align="left"><b>Note: </b>If tool-tips are enabled in your browser, then if |
| you pause the mouse over any cell, you will see the name of the character and |
| a representation of the sort key. In this representation, the separators |
| between the weight levels are represented with "|".</p> |

| <table> |

| <th>*</th> |
| <th class="x">In some cases, the UCA data table also includes contractions.<br> |

| <h3><b>Notes</b></h3> |
| <ul> |
| <li>The UCA results are versioned <i>both</i> by the version of the UCA <i>and</i> |
| by the version of The Unicode Standard used to process the data.</li> |
| <li>These charts only provide one of the alternatives for handling variable |
| characters (punctuation), whereby these characters are <b>non-ignorable.</b></li> |
| <li>Characters from large blocks, such as CJK-Ideographs, Hangul Syllables, |
| Private Use Area, etc. are represented by a sampling.</li> |
| <li>Some unassigned code points, noncharacters and other edge cases are also |
| added to the list for comparison.</li> |
