u1 - SVG: Scalable Vector Graphics 编辑

Deprecated since SVG 2

This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

The u1 attribute specifies list of Unicode characters (refer to the description of the unicode attribute of the <glyph> element for a description of how to express individual Unicode characters) and/or ranges of Unicode characters, which identify a set of possible first glyphs in a kerning pair.

If a given Unicode character within the set has multiple corresponding <glyph> elements (i.e., there are multiple <glyph> elements with the same unicode attribute value but different glyph-name values), then all such glyphs are included in the set. Comma is the separator character; thus, to kern a comma, specify the comma as part of a range of Unicode characters or as a glyph name using the g1 attribute. The total set of possible first glyphs in the kerning pair is the union of glyphs specified by the u1 and g1 attributes.

Two elements are using this attribute: <hkern> and <vkern>

Context notes
